Welcome to Eden

A hundred young people, very active on social networks, receive an invitation to attend a party on an island called "Edén" organized by a brand of drink. There, a mysterious adventure begins for them through the question "Are you happy?
Zoa (Amaia Aberasturi), who is trying to escape her drug addicted mother and absent father, accepts the invitation. Her best friend Judith invites herself, which goes against the contract Zoa signed.
Those who accept the invitation begin an exciting adventure, realizing that it will change their lives. But little by little, they will also discover that paradise is not what it seems... Zoa wakes up the next day to find that she and four others are the only people left on the island. Zoa, Africa, Ibon, Charly and Aldo, who are suspicious, are invited by Astrid, the chief, to stay on Eden. Judith wakes up alone and disoriented, but she is quickly seized by an invisible assailant.
