While on vacation, the Saint discovers a much-sought-after music box.

George Sanders makes his final appearance as crook-turned-detective Simon Templar, a.k.a. "The Saint," in The Saint in Palm Springs. The gimmick in this one is a set of rare stamps, smuggled from England. Wendy Barrie is the true heir to this treasure, and the Saint is engaged to protect her and the stamps. Our hero meets Barrie in a posh Palm Springs resort, where a gang of homicidal thieves have converged to relieve the girl of her inheritance. Three murders and one kidnapping attempt later, the villains are foiled by the Saint, with the aid of his onetime partner in crime Pearly Gates (Paul Guilfoyle). The Saint in Palm Springs is the sixth in RKO's series of films based on the character created by Leslie Charteris.

Suave soldier of fortune Simon Templer gets mixed up with a gang of counterfeiters who've murdered and robbed an European count of 1,000,000 pounds. He is aided reluctantly by Scotland Yard inspector Teal, who's convinced that Templar himself pulled off the heist, and less reluctantly by light-fingered Dugan and dizzy socialite Penny Parker.

A private detective goes after the people who murdered his girlfriend.
