Dennis pleads with Jim to untangle him from a timeshare con, without Dennis' boss, Jim's nemesis Lt. Diehl, finding out his wife has purchased one, too. Rockford's a lot more interested when a friend of Dennis' (who's also an unhappy vacation homeowner) proves very helpful, and happens to be a gorgeous single blonde. Jim recruits his father and Angel to out-scam the scammers.
