The new Netflix thriller from Spain shows young adults get abandoned on an island combined with a weird cult. Two days earlier, Zoa, who lives in Barcelona gets a random text asking “Are you happy?” The text comes from a computer bank in a bunker; a woman named Astrid (Amaia Salamanca) wants to find the biggest influencers to invite to a party for her new product, Eden Blue. The five worthy attendees, who are pre-picked by Astrid, aren’t going to be able to leave. Zoa’s friend Judith convinces Zoa make her a plus-1 to this rager, despite Zoa signing a contract. As they are led by a drone to a warehouse, they meet some of the other attendees: A goofy dude Aldo (Albert Baró), a quiet, intelligent guy named Ibón (Diego Garisa), a guy named Charly (Tomy Aguilera) and África (Belinda Peregrín), a mega-influencer. The party is free-for-all, with people splitting off to exploits. Judith finds out one of the workers being attacked and drowned in a barrel of water. The five “chosen ones” get to try the Blue Eden drink, but little do they know that the drink is spiked, which ends up blocking out most of the memories from that night. They wake up the next morning, completely hung over. No one else is on the island. A drone leads them to a compound, where Astrid, her husband Erik (Guillermo Pfening) and other workers from the party greet them.
