When Cade Kellerman and his gang bungled their robbery of a train and killed more than twenty passengers, they could not have known that the husband of one of those killed was himself a former bandit, who would stick at nothing to revenge himself on those he blamed for the loss of his wife. Together with an idealistic law student, Ben Walters sets out to track down and bring to justice the Kellerman Gang; even if he should lose his own life in the attempt.
