It’s 1934, and nightclub singer/evangelist Reno Sweeney is en route from New York to England on the ocean liner S. S. American. Her pal Billy Crocker has stowed away to be near his love, Hope Harcourt, who is engaged to the wealthy Lord Evelyn Oakleigh. With the help of disguises, tap-dancing sailors and good old-fashioned blackmail, Reno and Moonface Martin (Public Enemy #13) join forces to help Billy in his quest to win Hope’s heart.
