But the contest isn't over. The wagoner's son, Luke "Tomahawk" Callahan, has returned to Hansen's Bend after five years as an army scout. He knows nothing about the rail boss's challenge or his father's murder--until he sees the newspaper headline: "The Last Wagon Train?" The pretty lady journalist who wrote it wants to ride along and follow this story to the end. And of course, Tomahawk wants to defend his father's honor and avenge his death. But Arbuckle has sent his henchmen to sabotage the wagon train to make sure Tomahawk and his wagons are dead on arrival.
