No matter the odds, U.S. Marshal Alvin LeRoy always completed his assignments. That's why they sent him after the Reno bunch. LeRoy was single-minded once he was on the trail. He wouldn't back down and had a fearsome reputation for always finishing what he started. His pursuit took him across southwest Texas, where he faced up to bushwhackers and the aftermath of a massacre as he relentlessly tracked down and dealt with the baddest bunch he had come across in quite a while. Following a trail of deception and danger, he eventually ended up in New York. Here he faced the menacing top man of the crime syndicate who was behind the whole affair, and didn't stop until there wasn't a man left standing.
