Saboteur

Aircraft factory worker Barry Kane (Robert Cummings) is accused of starting a fire at the Stewart Aircraft Works in Glendale, California, an act of sabotage that killed his friend Mason (Virgil Summers). Kane believes the real culprit is a man named Fry (Norman Lloyd) who, during their efforts to put out the fire, handed him a fire extinguisher filled with gasoline, which he passed on to Mason. When the investigators find no one named "Fry" on the list of plant workers, they assume Kane is guilty.
