Billy finds fresh trouble when he falls in with a character called Alias. He kills a man in self-defence and ends up on the run, and then in the arms of a young woman – who also happens to be the girlfriend of Jesse Evans.

Billy bumps into a new character called Pat Garrett, who is riding with Jesse and the 7 Rivers Gang. Billy joins them – but law makers are already closing in. They plan to flee to Lincoln County – but not before Billy fulfils one last promise.
