Heroes of the Street

When a smart-alec street kid's father, a policeman, is killed in the line of duty, the boy turns over a new leaf and goes to work to support his mother, brothers, and sisters. He gets a job as an usher in a theater but really wants to become a policeman to avenge the death of his father. He soon finds himself involved in a fake kidnapping, real gangsters and a tip on the identity of the man who killed his dad.
