Belle likes to think herself immune to the dizzying effects of fabulous wealth. But when her best friend, Summer, invites her on a glamorous getaway to the Mediterranean aboard her billionaire boyfriend's yacht, the only sensible answer is yes. Belle hopes the trip will be a much-needed break from her stalled acting career and uniquely humiliating waitressing job, but once she's aboard the luxurious Lion's Den, it soon becomes clear this jet-setting holiday is not as advertised. Belle's dream vacation quickly devolves into a nightmare as she and the handful of other girls Summer invited are treated more like prisoners than guests by their controlling host-and in one terrifying moment, Belle comes to see Summer for who she truly is: a vicious gold digger who will stop at nothing to get what she wants. Belle realizes she's going to have to keep her wits about her -- and her own big secret closely hidden -- if she wants to make it off the yacht alive.
