The fifth action-packed Western adventure in a series from Alfred Wallon! U.S. Marshal Jim Kennedy is traveling with his prisoners, Jonathan Hancock and Dan Cochran, on the night train to San Angelo. He is scheduled to reach his destination in the early hours of the following morning. Kennedy has no idea, however, that the bosses behind the El Paso Ring have long known what Kennedy is planning—and they have already devised an insidious plan. The tracks are to be blown up at a specific point, preventing the train from continuing its journey. Kennedy is unaware that the passengers boarding at a loading station have something to do with it. When a thunderous explosion destroys the tracks and men storm the train, Kennedy and his companions find themselves in dire straits because the other passengers who boarded along the way are also part of the gang. Hancock and Cochran are freed, and three marshals are seriously injured in the process. But Kennedy doesn't give up. He sets out to pursue the fugitives, knowing how important Cochran's confession is to him. A dramatic chase begins!
