Nikki Martin (Lily Pons), a Parisian opera star, takes off in search of adventure and true-love, leaving her arranged husband to be at the altar. While hitchhiking, Nikki meets handsome American musician, Windy McLean (Gene Raymond) and his band, the 'McLean Wildcats.' Windy immediately spites her, but Nikki falls in love with him and follows him to New York by stowing away on the ship his on. The ship's purser (Edgar Dearing) finds her hiding in Windy and the Wildcats room. She is locked up by authorities, and Windy and the band are fired. When the ship reaches New York, Nikki escapes off the ship and finds out the Wildcats apartment. They demand her to leave, fearing being implicated but she refuses. Claire (Lucille Ball), Windy's girlfriend shows up with Hammacher (Herman Bing), and offers the band a low-paying job at a roadhouse in another city. Anxious to depart, they accept. Nikki becomes the band's singer. Claire becomes jealous and reports her to the authorities, causing the band to flee again.
