When Kit disappeared at a party and was found drowned in the quarry the next day, Clem knew who to point the finger at: herself. She was the last person to see him alive, the last person who could have helped. If she had just kept a closer eye on him instead of her crush, Jake, maybe Kit would still be here. She knows she made a mistake, and wishes she could just forget about it — but Clem’s friend Ellie says she’ll expose Clem’s secret if she doesn’t play along with Ellie’s lies. Jake seems to have his own difficult secrets, and when he and Clem start to talk, they make a plan to help themselves move on. But when an unexpected discovery at the quarry makes everyone question what they they knew, Clem and Jake decide it’s up to them to uncover the truth.
