It was a party. It was meant to be fun. But when Rachel wakes up, she’s in a strange room. Her clothes are on the floor. She can barely see straight. There are bruises on her arms. Stumbling downstairs, her friends are vague and embarrassed about something. They won’t say what went on, but something clearly happened. Why did her husband walk out of the party, leaving her alone? Little by little, Imogen begins to realise the people she once thought of as friends may have something to hide. So what happened the night before? If Rachel had been attacked, she’d know, wouldn’t she?
