Popular patrolman Danny Moore fails of promotion when he stops to aid an injured child and lets several thugs escape. When Danny is later informed of the plans of a criminal gang to rob Jack Griffen's bank, he gets departmental permission to set a trap and rounds up the robbers, gaining himself his promotion at last. It is a hollow honor, however, for, along with the thieves, he had to arrest his own daughter, Mary, who seemed to be an accomplice of the thieves. Jack Griffen, who is in love with Mary, comes forward, however, and proves the girl's innocence. Danny gets his sergeant's stripes, and Mary and Jack make plans to get married.—AFI
