Esther Williams, Peter Lawford, Ricardo Montalban, Jimmy Durante, Cyd Charisse, and bandleader Xavier Cugat star in this highly successful musical comedy. Actress Rosalind Rennolds is shooting a song-and-dance film in Hawaii when a young Navy lieutenant is brought onto the production as a technical advisor. Having once performed a number with her in an Armed Forces show, the young officer is convinced he and Rennolds should be together--so he spirits her away to a desert island.
