Adam lives a picture-perfect life: happy marriage, two young children and a flourishing career as a doctor. But Adam also lives with a secret. Hospital CCTV, strangers’ mobile phones, city traffic cameras – he is convinced that they are all watching him, recording his every move. All because of something terrible that happened at a drunken party when he was a student. Only two other people knew what happened that night. Two people he’s long left behind. Until one of them, Clio – Adam’s great unrequited love – turns up on his doorstep, and reignites a sinister pact 24 years in the making.
