Invasion

In the series pilot, aliens surface in Florida after a hurricane and assume human form, alerting the suspicions of an Everglades Park ranger, whose ex-wife is behaving strangely.

Fears of aliens are renewed by bizarre skeletal remains, a child's anxieties and the discovery of a strangely wounded airman, found in the wake of a devastating hurricane that struck the Everglades.

An underwater attack on Jesse involves an orange light; and an unexplained Air Force presence smacks of a cover-up to Larkin, who feuds with Underlay.

A deadly virus surfaces that may be tied to runaway baboons, hunted by Russell and Underlay in the Everglades. Still, an alien presence is palpable and manifests itself in mysterious ways, including another appearance by that ominous orange glow.

A shooting rattles Russell, who's further unnerved by Underlay, who's deceitful in the death of Russell's co-worker. Meanwhile, conspiracy fears fuel Larkin, reunited with an old flame in the Air Force whose veiled threats indicate a cover-up.

Mysteries drive Russell to fish for a luminescent being in the hope of catching an alien. Elsewhere, Derek loses interest in Kira and sets his sights on Mariel.

An SUV spill imperils Larkin, who's lost in the Glades. Seriously injured and fearing for her unborn child, she must depend on the kindness of a mysterious stranger, who gives her a lift. Meanwhile, a desperate search is launched by a fretful Russell, who's accompanied by Dave.

Dave identifies the skeleton found at the site of the plane crash; Larkin continues to look into the circumstances surrounding her accident.

People who went missing during the hurricane form a support group that meets at the church, and Dave looks for evidence that they are somehow different than they were before. Meanwhile, Russell investigates toxic zones in the Everglades, where everything died after the storm.

Dave is abducted after he posts on the Internet that a piece of an alien life-form was found inside a dead alligator. Russell finds Dave's tape recorder with the notes for his last blog and heads out to find him, but not before sending Larkin and the kids to a motel 20 miles away.

Russell confronts Mariel about how the hurricane has changed her; Underlay invites Dep. Sirk into his home to recuperate; and Jesse meets a lovely but odd girl while on vacation with Larkin and Rose.

Sheriff Tom Underlay takes his stepchildren to a remote cabin for a getaway, but he has another agenda for the trip. Meanwhile, the residents' fears grow over who is a "hybrid"; and Russell and Mariel worry about their kids' safety.

Sheriff Underlay is shot three times in an episode that flashes back and forth between 1996, in the aftermath of the plane crash, and the present, in the wake of the shooting. Elsewhere, Larkin threatens to announce that the sheriff and his wife are "hybrids," much to Russell's chagrin.

Underlay recovers from his gunshot wounds sooner than expected and launches the investigation into who shot him. Meanwhile, someone or something is stealing Dave's belongings.

Kira Underlay decides she wants to "join the new club" by going into the water. Her dad tries to stop her, but the sheriff can't keep her from spending time with some dangerous companions. Russell runs some tests on Mariel, giving them new information about being a "hybrid."

Underlay and Russell go after Christina and Derek for attacking Russell's friend Mona. And Christina, who is a couple of weeks pregnant, is showing as if it were five months.

The hunt is on for a pregnant Christina, with Russell, Szura and Underlay all looking for her. And Russell also wants to find Szura, who he believes killed Healy.

Russell and Dave investigate what's happening on Szura's island in the Keys; tensions rise at school between students who were changed by the hurricane and those who weren't; and Underlay tries to find out the extent of the military's involvement in post-hurricane changes.

The hybrids' highly evolved instincts become apparent; Szura and his recruits leave the island in the Keys; and Jesse is involved when violence breaks out between humans and hybrids.

A hurricane is forecast to miss Homestead, but the hybrids know better. Meanwhile, Sheriff Underlay tries to imprison Eli Szura.

Homestead is hit hard by Hurricane Miranda; Sheriff Underlay and Russell find out what Szura is up to, and it is beyond their worst nightmares.

Szura's hybrids continue to implement his master plan during the hurricane, but evacuees Dave, Larkin, Jesse and Rose encounter problems with some humans, too. Meanwhile, Underlay and Russell work to thwart Szura's scheme.
