While on vacation the family witnesses the discovery of a murder victim buried in the sand. They attempt to help the local authorities and are rebuffed by the sheriff whom is slightly miffed at vacationers putting their noses in his business. The sisters and their husbands go on a quest of their own to solve the case, but they have one slight edge the police don't.
The husbands secretly take pictures of the body and then have a difficult time finding a place to get them printed. Dropping their parents off at the Casino in Little River, they drive to a techie store in Myrtle Beach and have everyone working in the store gawking at the photos.
Upon their return they discover Blue, Kate and Ell's show cat, has gotten out of the beach house and is nowhere to be found. The family is beside themselves with worry and rightfully so with a murderer on the loose, and little do they know once he is found he will bring them face to face with the murderer.
