Only feeling slightly embarrassed about the amount of luggage she packed, Marlene refuses to leave anything behind. Bethany is giving a lecture at the Murry Hills Resort and asked Marlene to assist with the presentation. Having gone on short, seemingly innocent trips with her sister in the past, discovering bodies and experiencing life threatening situations, Marlene isn't taking any chances. This seminar proves no different. A woman in the audience is found dead at the end of the lecture and her body disappears from the locked room before the police arrive. On the short list of suspects, the sisters need to solve the murder before the police build a case against them.
