Arriving by cattle car with two of his beloved horses, Jesse Derringer is not your typical railroad employee. With the eyes of a scout, he looks for trouble before it becomes a problem for the construction crews,and sometimes starts trouble himself. Usually he handles hot-tempered troublemakers with a cool head and steady hand. But then there are problems that are more complicated and it's Derringer's job to defuse them, before they ignite a full-blown bloodbath.
