When the plane carrying the 5 most famous lads in the world, namely One Direction, crashes somewhere in the Caribbean the world mourns, convinced that they're dead.
But all 5 have made it to an island, totally deserted aside from the small hut occupied by seventeen year old Serena Harris and her little sister Quinn, who survived a plane crash the previous year.
The fight for survival is on and the boys team up with the girls, in a desperate attempt to get back home.
