Catalina Caper, also known as Never Steal Anything Wet, is a 1967 comedy musical mystery film starring Tommy Kirk.

About half of the film involves swimsuit-clad adolescents dancing on yachts in various montages set to the singing of Little Richard, Carol Connors and The Cascades.

When they are not dancing, Pringle and his friends investigate the scroll's theft and discover that the parents of one of the boys are responsible.

They also attempt to woo a mysteriously depressed young woman, Katrina Corelli, from her vaguely threatening fiancé Angelo.

[1] Produced by Executive Pictures Corporation, formed by Bond Blackman and Jack Barlett, it started filming in September 1965, on Catalina Island.
