Lone super-quick gunslinger "nameless" Cowboy (Estevez) is on the run from a rancher (Long) and his men, who are out to kill him for killing the rancher's son. A former Confederate soldier (Forsythe) sees how can Cowboy defend himself, even dropping a drink, pulling and shooting a
guy, and catching his drink before it hits the floor. Cowboy gets mixed up with this soldier who has knowledge of hidden gold. So, Cowboy and Dooley, the Soldier tries to complete their map and find the gold because Dooley has only one part of the map. And also Col. Skinner (Redleg commander) on the tale of Dooley.
When Cowboy and Dooley free a man (Lauter) with part of the map to the gold, they then are also pursued by Spanish soldiers. It all leads to a small Mexican town terrorized by soldiers and led a by a good priest (De Almeida) who is another one which has knowledge of the hidden gold.
