The film stars Giuliano Gemma (billed as 'Montgomery Wood') alongside Fernando Sancho, Nieves Navarro, George Martin, Antonio Casas, José Manuel Martín and Hally Hammond.
In a desperate attempt to deter their pursuers, they decide to hold the family hostage threatening to execute two a day until they are allowed to go free.
He decides to enlist the aid of Ringo, who agrees to infiltrate the gang and free the hostages in exchange for his freedom and a percentage of the stolen money.
He manages to successfully join up with the gang, posing as a fellow outlaw on the run, however Ringo's plans quickly become complicated as Sancho begins ordering the execution of hostages as well as the tension within the house as Delores, Sancho's woman, encourages Major Clyde's romantic feelings while one of Sancho's men begins making advances towards Major Clyde's daughter, Ruby.
Encouraged by the success of Sergio Leone's A Fistful of Dollars the previous year, which he had helped write, Duccio Tessari decided to produce his own western.
There is more humorous theme, and at times uses slapstick comedy, compared to usual Spaghetti Westerns.
The cast, both leading and supporting roles, were primarily made up of Italian and Spanish actors including Montgomery Wood and Hally Hammond, born Giuliano Gemma and Lorella De Luca respectively.
The film retained its original title for the most part, however it was also re-titled as Ballad of Death Valley in the U.S. and Ringo: The Killer elsewhere.
