Jim Jepson returns home after serving five years in prison for bank robbery. He manages to live a straight life with his wife and little daughter until misfortune overtakes him. His wife dies, his daughter is forced to work for her living, and at this crisis in his affairs, he meets one of his former pals, Doc Burns, a jailbird, who is wanted in the west for another robbery. Jepson, who has become discouraged, is persuaded by Burns to resume his former life. They rent an old house next to a bank, tunnel through the cellar to the bank, working at night, while Mary, innocent of the life her father leads, continues her work as cashier in an all-night restaurant. Mary, returning home late, is saved from insult by Bob Darrell, a detective, who escorts her home. A man seen loitering in the vicinity, is recognized by Darrell, as "The Worm," a notorious crook.
