The Institute

The Sanctuary meets Shutter Island in this high-concept psychological thriller from the acclaimed author of The Sisterhood.

BIRDS OF A FEATHER FLOCK TOGETHER
BUT SOME FLY TO THEIR DEATHS

A group of students step off a platform into the path of an oncoming train.

Billie is the only one who survives.

She doesn’t remember what happened.
But she knows this: they weren’t suicidal.

At the secretive Arbor Institute, Billie is told she’s suffering from ‘flock phenomena’ - a terrifying impulse to self-destruct as part of a group.

If it happens again, she won’t survive.

Cut off from the outside world, watched at every turn, Billie starts to realise the truth:

The Institute isn’t here to help.

And the girl they think they’ve contained?
She’s not prey.
