Curro Jiménez, nostalgic, decides to go see his old mother. There he meets a young woman who helps the old woman, apparently selflessly. Actually, this is a spy sent there by an enemy of the bandit.

Curro and his men go to an arms purchase deal but the dealer's nephew kills him and blames Curro Jiménez.

Curro rescues a white horse and returns it to its owner, an ex-mercenary who is looking for work with his wife and son. The work offered him in a farmhouse is simple, must meet a band of murderers and finish with Curro and his guys.
