Everyone has secrets. Even your daughter…

The morning after a glamorous, luxury wedding, you and your best friend go to wake your twenty-four-year-old daughters. You open the door to their shared room in the pool-house and find a lamp smashed on the floor, a blood stain on the carpet, a ringing phone – and both girls are nowhere to be seen.

The police come and you discover something shocking. Something inexplicable. Is one of your daughters trying to kill the other? And that’s when you and your best friend begin to unravel what's really going on between the girls.

You need to work together to find your daughters, testing your friendship to its limits. And you can’t help but wonder: which girl is the killer and which is the victim?
