Los Angeles aircraft worker Barry Kane (Robert Cummings) evades arrest after he is unjustly accused of sabotage. Following leads, he travels across the country to New York trying to clear his name by exposing a gang of fascist-supporting saboteurs led by apparently respectable Charles Tobin (Otto Kruger). Along the way, he involves Pat Martin (Pricilla Lane), eventually preventing another major act of sabotage. They finally catch up with Frank Fry (Norman Lloyd), the man who actually committed the act of sabotage at the aircraft factory.
