Underworld

The film opens at an all-black college somewhere in the Southern United States. Paul Bronson, a recent graduate, is convinced by gambler LeRoy Giles to join him in Chicago. There, Paul becomes involved with Dinah Jackson, a singer who is married to club owner Sam Brown but has been having an affair with LeRoy. Paul runs into Evelyn Martin, a beauty parlor owner, who recognizes him from college. The two have lunch together, during which LeRoy spots them and reports to Dinah that Paul is seeing someone else. Dinah arranges for LeRoy to drug and rob Paul. LeRoy also kills Sam and leaves the gun by his body. Paul finds the body; as he picks up the gun, Dinah enters and accuses Paul of killing Sam. Eventually, Dinah reports Paul to the police for the murder; she then goes on a bender and dies when her car is hit by a train. It seems that Paul will be found guilty of Sam's murder, until, at the last moment, a Chinese man named Ching Li comes forward as an eyewitness. Paul is freed and reunited with Evelyn. The two plan to travel by train to Oklahoma to start over together.
