In an airplane factory in California during World War Two, a fire breaks out. Even though he loses his friend in the fire, Barry Kane (Robert Cummings) is accused of being the saboteur. He must run for his life to avoid being prosecuted. But, in order to clear his name, he must prove that Frank Fry (Norman Lloyd) was the real saboteur. As he chases this villain and others involved in trying to destroy American military power, he encounters Pat Martin (Pricilla Lane). He needs her to help hide him as he is being pursued by police. She distrusts him at first. But as her love for him grows, she gets involved in his chase and trying to clear his name.
