Baywatch

Mitch feels that he needs to "find himself", so he travels to Hawaii to have some time off. While on the beach in Hawaii, Mitch rescues a family in trouble, but he barely makes it. He then realizes that he would have saved them all much more effectively if he knew more about the currents and these waters in general. He sets out to begin Baywatch Hawaii, an international training camp for lifeguards. He has to pick out the best of the best, and make a perfect team to start out with. Meanwhile, Jessie realizes that she has some competition for J.D. after he meets Kekoa.

The Baywatch team moves in and gets acquainted, and they're all introduced to the new training routine. Sean makes them jump off a huge cliff as a startup, but none of them gets scared. Later on they face some problems with the personal differences between the team members; J.D. is an organization freak while Kekoa and Jessie are already fighting. Mitch saves Hina, a former victim, from a secondary drowning. Later on, Mitch and Sean plans a team exercise that's going to put all the lifeguards' corporative skills to the test.

Dawn Masterton, a specialist in the human body, joins the team, but the other members are not confident in her skills. When they start off with an exercise led by Dawn herself, she blacks out, and the other team members have to rescue her. Dawn and J.D. later discuss how they should handle their little secret, that they know each other from before, and decides to keep it secret. Dawn manages to annoy Jessie with initiating that Jessie does not have a chance against her when it comes to J.D. Mitch and Tanner joins Allie on a helicopter ride, but it ends pretty soon when they notice a possible victim waving at them from shore nearby. Later on, Tanner meets a girl who wants to teach him to ride the waves on a board. He then discovers that she's really sick and wants to end her life. J.D. gets to ride the boat "America's Cup" and makes it to the team, but he turns them down. In the end, Sean wants to cut Dawn from the team, but Mitch refuses, so he gives her an underwater challenge she passes perfectly.

Mitch and Tanner visit Shark Island and a mysterious man who lost his son there appears in front of Tanner. Meanwhile, the lifeguard team performs a big mistake when assisting the Coast Guard in a rescue, which leads to a new kind of training for the team. Allie meets Nick Montgomery, a rescue swimmer working for the Coast Guard, and finds him fairly attractive. Kekoa flirts a lot with J.D., which pisses Jessie off completely. Later on, Sean tells Jessie about his attribution to nude swimming, and she decides to try it. After a while, a swimmer nearby gets in trouble, and Jessie has to save him. In the end, they returned to the new training involving the Coast Guard. Jason is chosen to wear blacked out swim goggles because Sean finds him to self-reliant. He then gets placed on a cliff without knowing where he is. By accident, Sean, who's hiding close to Jason to make sure that he's safe, gets a rock in his head and needs a Coast Guard rescue. Jason has to take of the swim goggles and help him, even though he knows that he might lose his job by doing so.

Baywatch teams up with the Coast Guard to search for a group of kids in the water. They all have to search in caves all they, but they still can not find all the kids. Allie is filming the caves with a camera with an infrared sensor to see what they have. When night falls, there's still two kids missing, but after watching over the film from their camera, they see what they think is a hand in one of the caves. They then decide to go out at night looking for the last ones, but soon discovers that the victims have been swept into another cave via an underwater channel.

The Baywatch team go on a weekend getaway to the Waimea Valley. Jessie and Kekoa are still fighting for J.D., and he loves it. After a while, they decide that they should stop being childish and start sorting stuff out, which they manage to do. When going paddling, Jessie and Kekoa have to save a man trapped in a waterfall by working together. Jason and J.D. are going to check out girls, but they do not have much success. Meanwhile, Allie and Sean search for treasure, but end up in some kind of graveyard.

The new training center is finally done and ready to be boarded. Jason's individuality becomes a problem as he performs a way to risky jet ski pickup, so Sean wants to dismiss him from the team. After talking to the other lifeguards, Sean decides that he'll try to teach Jason some risk management; basically the skill of preventing accidents - on the sand. Jason learns and does his job perfectly, but three guys would not listen to him, and one of them breaks his neck. Meanwhile, Dawn outstays her welcome when she joins Nick and Allie in their private helicopter ride. All of a sudden they find a boat with no crew, and later find out that a pregnant woman went into labor after falling overboard.

Hobie is suddenly getting married and Mitch needs to stop the wedding. Meanwhile, Sean notices that Kekoa hesitates a lot like she's afraid to commit to the team, and demands that she finds out why before she gets someone killed. She thinks it's because she's so afraid of failure, something she's been afraid of for a long time. Mr. Tanaka, her father, wanted a son, but he got her instead, so she's always tried to be the best athlete - and she's made it. That is until she joined Baywatch, where all the people are top trained, which leads to her decision of leaving Baywatch since she does not think she can change something that goes this deep. Before everything is settled with Kekoa deciding to leave the team, the lifeguards have to make a difficult rescue to a victim trapped in an underwater cave. Kekoa has not left the team yet, so she helps out as best as she can. When performing CPR she breaks down completely before the victim wakes up, and realizes just how much of a difference they've done this day. In the end, this means that Kekoa overcomes her fear of failure.

Jessie and Jason notice a shark coming way too close to shore on their watch. When they're unable to scare it away with the jet ski, they dive down to see that the shark fins have been cut straight off. Both of them find themselves emotionally affected by this, and Jessie sets out on a personal mission to stop a shark hunting boat in the area. Jason feels that he has an emotional connection to the shark, so he decides to visit one of the true Hawaiian men to figure out what he's experiencing. When Jessie tries to stop the people hunting sharks, they throw a whole lot of shark bait on her after ruining her jet ski. The lifeguard team comes to save Jessie and Jason proves himself as a true kama'aina - a person belonging in the Hawaiian family.

The team becomes obsessed with money-lust for a sunken treasure. Their argument about who the unfound treasure belongs to sets Sean off; he thinks they're destroying the team. Jason convinces Sean to permit their treasure hunt by referring to it as a scuba diving exercise and succeeds. The Coast Guard rescue swimmer Nick helps Allie find the areas where they'll most likely find a ship, but warns her that it's very unlikely that they'll be able to locate anything. Sean confronts Dawn with her lack of engagement to the team, and expresses his wish for her to step out of the sideline and into the game. Later on, they are able to locate the sunken ship and dive down to it, but the search becomes dangerous when Jason causes a torpedo to shake loose at the site.

An experimental submarine and its passengers ends up in a devastating tragedy for Allie, who finds & loses love all too quickly. She finally learns to trust Nick, a rescue swimmer working at the U.S. Coast Guard; a man she's been into for two weeks. Nick takes some huge risks when trying to save the passengers in the submarine, which unfortunately leads to him getting a severe case of the bends. He never wakes up, and Allie is devastated. Mitch arranges a lifeguard memorial service for Nick. Mitch tells her "Nick wasn't a lifeguard, but he died being one."

Jason experiences success during a training exercise with the often lifeguards, able to find "the path of least resistance" - being underwater instead of swimming with his head over water. J.D.'s inventions pay off, as he performs a daring underwater rescue. Jessie and Allie become parents for a day after they come across a boy who has lost his mommy. Also, Dawn deals with a painful memory of a life and death choice from her past, as a lawsuit comes her way. Sean promises to fix the mess she's in, and he's able to do so pretty easy. They all get to know that J.D. and Dawn knew each other from the past, which makes the relationship between J.D. and Jessie even more complicated.

Dawn rescues a man, underwater for over 20 minutes, and tries to learn his magical secret. The doctors said his body "shunted", something Dawn knows a bit about from before. Meanwhile, Jessie, Kekoa and Allie spend a girls' night out after spending the day shopping - all because they feel that they all need to cheer up. Kekoa can not seem to find the right guy, Allie is missing Nick (who died in S10E11, "Bent"), and Jessie needs a day off. None of them would expect that it all ends up with a rescue off the side of a cruise ship while they're all in their underwear. Later on, Sean shows interest in the secret of the man who survived 20 minutes underwater, and Dawn decides to show him a special emerger technique she learned in India, giving them a weird underwater experience Sean finds quite frightening. In a rescue at the end of the episode, Dawn gets trapped underwater, and tries to make her own body shunt. After several minutes underwater, Sean is able to get her out and make her heart going again after performing CPR.

Sean and Jason encounter Jenna for the first time, in flirtation and innocence as Sean spills a lot of shave ice on her breasts. They then realize that Jenna's plans for the team will actually make life on the station more difficult. Later on, environmental activists starts a protest against the radioactivity in the air, craving attention from the public authorities. Jessie and J.D. finds themselves alone on a beach they're supposed to watch for the whole day, seeing this as an opportunity to discuss their personal issues with each other. After they have finished their watch, J.D. is set to be the judge for a beauty contest - to Jessie's disdain.

In the beginning, his granddaughter detests Jason, but as Jason learns to respect their old traditions, the mood changes, and they begin a romantic flirtation. While all this is going on, Sean's dating Jenna, ending with a dinner. In the middle of it, Jenna starts talking Sean into giving her more rights when it comes to the training center, which makes Sean run off angry.
