Jessie Hampton has a dilemma; she has a treasure map, and someone is trying to kill her. Jessie's boyfriend Alan asks Jon, Lois, and Brian to help locate the treasure, but before they can begin to look, a powerful Pacific storm isolates them. Tempers are flaring within the small group when suddenly they hear a distant cry for help, and discover Christie; Jon's jealous wife has been murdered. Later when the police arrive, they find Christie's body is missing and no evidence of a crime, so they write it off as a hoax. Lois suspects that Alan might be involved and calls Jessie to discuss her thoughts. They decide to investigate and soon find this is a serious mistake when they walk into the murderer's trap.
