Big Brother meets Black Mirror in this high-concept thriller in which six strangers take part in a mysterious medical experiment in an isolated mansion.

Amanda Pearson was once the hottest rising star in the music world. Not anymore. Washed up, broke and directionless following a public breakdown, she is certain she will never be adored again. But she is very wrong.

Her old manager calls her out of the blue with an opportunity: a week’s stay at an isolated mansion with five strangers, all under constant observation. Every day they must take a pill. Five people will be taking a placebo, but one person will take an experimental drug that they are assured has no adverse side effects. So, what’s the catch? Amanda isn’t sure, but the pay is too tempting to turn down.

However, it soon becomes clear that this is no ordinary experiment. Each day Amanda discovers more about her fellow housemates, that the old mansion holds horrifying secrets, and that there is no way out…
