An outlaw named Big Sam Donaldson tries to disturb the peace between white settlers and the Sioux by selling weapons to the Indians. Buffalo Bill is assigned to stop this arms trade and prevent a war, in a West where alliances and suspicions keep multiplying.

How it was made

The film was directed by Mario Costa, who signed his work under the pseudonym J. W. Fordson. The screenplay was written by Ernesto Gastaldi and Luciano Martino, with music by Carlo Rustichelli and cinematography by Massimo Dallamano. Gordon Scott plays Buffalo Bill and Mario Brega plays Donaldson, alongside an international cast that includes Catherine Ribeiro and Hans von Borsody.

Reception and legacy

Critics were divided. Some praised its traditional style and convincing atmosphere, which one review compared favorably with routine American productions. Others found it a stereotyped western with heavy battle action and a portrait of its historical hero that strays far from the record.
