Middle-aged European pianist Paul Marvan (Hugo Haas) is brought to America by wealthy widow Diana Fowler (Mona Barrie) and he meets and weds a canary-blonde named Margo (Cleo Moore), who is a nightclub dancing partner to Carlo (Rick Vallin). Margo's trampy and flirty behavior inflames Marvan, who is also disturbed over increasing financial and professional straits, since Diana, his wealthy sponsor was more than a little perturbed after Marvan married the little tramp. He thrusts one hand into a printing press in hopes of collecting $50,000 insurance, but payment is refused when it is disclosed his mishap wasn't an accident. Margo returns to Carlo, and Marvan finds refuge in a Salvation Army shelter, now playing the piano with one hand.
