The Texan, a Civil War Veteran whose reputation of being the fastest gun in the west precedes him, roams across Texas from town to town, not looking for trouble; trouble finds him.

Bill is hired to drive a cattle herd to Abilene, but he must contend with two big problems: a hostile trail hand and a rival drive whose leader will stop at nothing to ensure that his herd gets to Abilene first.

After failing in an attempt to ambush Bill, Bishop pays a band of Native Americans to attack the Akins herd, hoping to scatter the cattle and prevent them from reaching Abilene first.

Bill is captured by a posse and accused of being one of the men who robbed a bank and shot the banker; only the sheriff, whom the banker hates for being in love with his daughter, is inclined to believe Bill.

Bill is sent into Mexico to investigate and put an end to a counterfeiting ring that's been operating there making phony American currency; the lawman he was to contact is ambushed and killed, leaving Bill to handle the situation alone.
