The first season's finale hinted at the second season's setup, in which, in addition to the girls, a group of adolescent guys became the puppet master's new test subjects.
The guys are shipwrecked on a new island, where they must battle for their lives. The group is being watched by the experiment's puppet master, who has carefully orchestrated the situation.
Following a plane catastrophe that leaves a group of young girls trapped on a desolate island, the drama series follows them.
The high school pupils are unaware that they are participants in a social experiment until they are rescued by the same individuals who put them there.
Season 1 concentrated on the girls' experiences on the island and in the bunker following their rescue.
