The Ritz Social Club, a Bowery cabaret, is the rendezvous of four old friends: Michael Angelo Cassidy, a trap drummer and composer; Buck, his arranger; Izzy, who breaks into politics; and Trent, who has become a gun-carrying gangster. Angie Miller admires Mike but surrenders to the proposals of Trent. Mike meets Marjorie Church, a society heiress, and 5 years later, having become a successful song writer, falls madly in love with her. Angie goes to Mike's apartment to congratulate him, and when Trent thinks she is unfaithful, he accidentally shoots her and hides the body. When the body is discovered, Mike is held for murder. Buck discovers evidence of Trent's guilt at the time Mike is convicted, and when Buck forces a confession from Trent, the judge reverses the verdict.
