A performer in a water ski show is blackmailing her former boyfriend. He will lose a multi-million dollar inheritance if he gets married before the age of 30, but she discovers he secretly got married to a rival in the water ski show. When the woman turns up dead, Cha Cha's nephew, who had an almost obsessive crush on her, is implicated in the murder.

While preparing to leave a tiny hotel Ken finds a young woman passed out in the hall outside his room. He revives her and discovers she is carrying $45,000 ransom money for her abducted boyfriend. Ken, against his better judgment, decides to help her ""negotiate"" with the kidnappers because she is $5,000 short of their ransom demand -- and she keeps fainting.
