LOL: Qui rit, sort!

Philippe Lacheau invites 11 new actors and comedians to a very special evening: they have to resist laughing for 6 whole hours. They get a yellow card the first time they laugh. The second time, it's a red card and elimination. And the contest gets off to a flying start with a group musical game suggested by the Mcfly and Carlito double act: the totally honest song!

The contestants spend the first hour of the game trying to put their opponents off their stride. Jérôme goes on the offensive and plays the first joker of the season, introducing a very special medieval dance troupe.

The game has been underway for 2 hours, and 3 competitors are already in danger. Philippe opts to reward the most aggressive player in these early stages with an ‘Armafifi'. The girls decide to go on the attack. Audrey relentlessly targets Jérôme with her joker, while Alison and Anaïde fake an argument in the hope of unsettling the other contestants.

After 3 hours of play, several yellow cards have been handed out, but still no elimination. So everyone goes on the attack! Alison unleashes her joker, a parody of a famous game show, and Audrey stages a very unusual musical challenge. So who will be the next to laugh?

After more than 4 hours of play, the first contestants are eliminated! Finally, Philippe Lacheau has some company in the control room. Things get trickier now for the remaining contestants with the introduction of the smile rule. And the eliminated players put the cat among the pigeons with the first act of revenge.

We're approaching the end of normal time, and the remaining contestants are determined to hang on. But the eliminated players are equally determined to get their revenge by returning to the game one by one and making them crack up.

They've now been playing for over 6 hours, and the last contestants are battling to the death. And the grand final is here. But for the first time on LOL, the staring-each-other-in-the-eyes-without-laughing game is interrupted by an amazing mystery guest! Who will manage to keep their composure and be declared the winner of Season 4?
