Zoe struggles with a secret as the Zimmerman clan sets out for a week of fun in the sun at Camp Carter, where they find the cook dead in the pantry on the very first day of their family vacation. Not only was Zoe the only person other than the victim in a blocked room, but when the police arrive she is standing over the body with a bloody knife in her hand. Zoe sets out to find the real killer with Zak's help. At first it seems like an easy task since the number of people at the camp at the time of the cooks death was limited, but as Zoe begins to dig deeper, she finds a history of unexplained accidents dating back years, that she begins to suspect weren't accidents at all.
