Cast & Crew
When valuable freight shipments are repeatedly stolen from the Cascade Pacific Railroad, chief railroad detective Blake suspects an inside job but can find no proof. His handsome son Jimmy comes for a visit and saves the lives of a group of children who were playing in a freight car and became trapped when the car took off out of control. Jimmy returns one of the boys, Jackie, to the shack where he lives with his sister Lois and grandfather, Rufe Marvin, a retired engineer. Jimmy accepts the pretty Lois's invitation to dinner and decides to stay in town for a while. While dining with Lois and her family, Jimmy notices that their kindling consists of broken-up packing crates. The crates bear the insignia of one of the companies that has suffered from the freight robberies, and when Jimmy questions Rufe, the old engineer states that he picks up his kindling from a nearby garage. Telling his father that he wishes to pursue this lead on his own, Jimmy obtains a job at the garage and quickly becomes suspicious of the owner, Herb Jackson, and railroad employee Hinton, who is in love with Lois. Jackson arranges for an "accident" to kill Jimmy, but the quick-thinking young man escapes being crushed to death by dashing into an old iron boiler. Hinton helps free the still suspicious Jimmy, who then meets with railroad official Curtis, whom Jimmy does not realize is the head of the gang. Curtis, intent on heisting a million-dollar shipment due in that night, has Jimmy kidnapped to get him out of the way. Jimmy is found by Rufe, who has overheard the robbers' destination. Rufe fires up his faithful old engine, "Minnie," and the men race along the countryside. Following a chase and fight, Rufe and Jimmy succeed in capturing Curtis and his gang, after which Jimmy decides to stay with Lois and the railroad permanently.
