Considered the quickest gun alive, Fast Larry Shaw works as a hired killer until his wife is slain. Although he longs to be reunited with her, he won't lie down for anyone. Then he slays one of the Katlin Gang, becoming a marked man. He plans to leave Willow Creek after helping soiled dove Rita Vargas identify the man who fathered her unborn child. One candidate is the infamous William Bonney -- or Billy the Kid -- who now wants Shaw back in the saddle fighting beside him in a cattle war.
