Dave Henderson, an orphan who has become the beneficiary of a rich man's will, falls in with race-track crooks Martin Tydeman and Bokky Sharvan who bilk him out of his $100,000 inheritance. In retaliation, Dave steals the money from Tydeman's safe, but is caught and sentenced to five years in jail. In prison, Dave becomes friendly with Millman, who is about to be released, and reveals the money's hiding place to him, arranging to rendezvous at the end of Dave's term. Once released, Dave is hounded by members of Tydeman's gang as well as the police, who are waiting for him to retrieve his bounty. While taking refuge at the house of Capriano, an old bomb maker, Dave falls in love with the old man's daughter Teresa. However, Capriano sets a trap for Dave, who awakens in a drugged state to find the $100,000 missing. With the help of Millman and Teresa, Dave recovers the money, turns it over to the police and resolves to go straight.
