Guests and staff alike are hiding secrets: a husband with an alibi that doesn’t track, a high ropes instructor with unexplained fresh scars, a new manager with a secret past. With hundreds of restless guests and staff on site, Nicola knows the clock is ticking to find the killer before they disappear for good.
