What happened in season 1?

contains some spoilers from season 1

Due to their past actions at home, eight high school girls were put on a plane that took them to a retreat where the main purpose was to learn about women’s empowerment. It took a dark turn when they crashed into the water and became stranded on an island. Viewers soon found out the plane crash was part of a social experiment and hidden cameras were placed all around the island to capture how these girls handled being in that situation.

The person in charge of the experiment, Gretchen Klein (Rachel Griffiths), explained to her donors that she wanted people to see that women could handle being in intense situations where they find a way to work together and create peace.

Throughout the series, the 10 episodes explained the backstories of each character as they spoke with two agents about their experience on the island in an undisclosed building. Two of the eight girls knew they were a part of an experiment, but could not let any of the others know.

What will happen in season two?

The first season left viewers on a cliffhanger. Leah (Sarah Pidgeon) discovered another similar experiment, but with boys instead of girls, as she tried to escape the mysterious building. The newest season will pick up where it left off.
