Five Thousand Dollars on One Ace (Spanish: Los Pistoleros de Arizona) is a 1964 Spanish Spaghetti Western film directed by Alfonso Balcázar, scored by Angelo Francesco Lavagnino and Don Powell, and starring Robert Woods, Fernando Sancho and Helmut Schmid.

Carrancho is set free, and in return saves Jeff from a snake with an expert knife throw.

As he walks through the desert landscape Jeff finds two dead man bound to the ground, apparently Carrancho's former friends.

Rossen and his men try to coerce Helan and David to sell their ranch, when Jeff and Carrancho appear.

Rossen sets fire to the ranch and Dundee turns Helen against Jeff by blaming him (who has helped them save the horses and the house).

Jeff recognizes Carrancho's knife left at the bank and finds the Mexican leading a stage hold up.

Two other ambushers further down the pass hear the coyote signal and shoot two men riding on horses.

The two arrive at the ranch to confront and kill men sent by Dundee to look for David (Helen had told the lawyer that her brother was alive).

In town Jeff kills Rossen in a gunfight while Carrancho and David shoots two men who were lying in ambush.

In his investigation of narrative structures in Spaghetti Western films, Fridlund writes that beneath the smooth string of action scenes in Los Pistoleros de Arizona a classical US Western plot - about a stranger protecting settlers against the villains - coexists with a different story: the unstable partnership between Jeff and Carrancho - appearing one year before For a Few Dollars More made this a standard theme in Spaghetti Western films.
