Ken is on the trail of two Apache children, entrusted to an old couple, Jacinto and Kayita, by their white mother kidnapped 12 years ago. The desire of the white grandfather, to track down the grandchildren of which he was unaware, will remain unsatisfied by the brutality of the world of the border. Ken will have to contend with the wrath of the Apaches, and defend an entire terrified country.
Ken is stopped with a patrol of soldiers waiting for the train carrying the payroll. Meanwhile, the train is robbed, and the hunt for the bandits is immediately unleashed. The two surviving bandits will be joined by the two surviving hunters in what promises to be a real "mess".
