An exclusive couples retreat turns deadly when the therapist is drowned at sea during her evening swim. When fingermarks are found on the victim's neck, Mervin confirms foul play was involved, and suspicion soon shifts to her clients - two couples who have paid a small fortune to mend their fractured marriages. But all four were having dinner together at the time of the murder, and while each member of the party slipped away from the table for a few minutes, there's no way any of them could have drowned their therapist in the middle of the ocean and made it back in time... is there?
Meanwhile, Mervin is determined to track down his brother, along with the possessions Solomon stole from him. But Mervin gets more than he bargained for when Solomon's attempts to make amends land them in hot water. Is it the end of the road for these belligerent brothers?
