No matter what the odds, US Marshal Alvin LeRoy always completes his assignments. That's why he's been sent after the Reno gang. His pursuit takes him across southwest Texas, where he faces up to bushwhackers and the aftermath of a massacre as he relentlessly deals with the baddest bunch he's come across in quite a while. A trail of deception and danger ultimately leads him to New York, where he confronts the menacing top man of the crime syndicate who's behind the whole affair.
