April Showers stars Jack Carson and Ann Sothern as a pair of small-time vaudevillians whose act gets nowhere until their young son (Robert Ellis) joins them. The threesome form a knockabout acrobatic turn which propels them into the big time. Jealous of his son's success, Carson takes to the bottle, and the act breaks up in a spirit of mutual recrimination. This being a Warner Bros. musical, the three family members are reunited for a sentimental climax. April Showers was based in great part on the vaudeville career of Buster Keaton, who chose after much consideration not to pursue the matter in court.
