The plot is usual in Spaghetti Western genre : a merciless vendetta , as a killer is contracted to murder , but the assassin fails to deliver, prompting a revenger to go after him instead . It delivers an absurd parallel within the stereotyped framework of the European Western , and revealing the sheer gratuitousness of traditional roles-types and ordinary mechanisms to create an uproarious genre critique . It provides an acceptable main and support cast . Fabio Testi gives a passable acting as a condemned killer who is hired by a railroad boss to murder an uncooperative rancher . While the gorgeous Jenny Agutter shows his beauty and charming face . As always , Warren Oates , Monte Hellman's regular , steals the show as the relentless avenger hubby . Support cast is formed by notorious secondaries as director Sam Peckinpah , SidneyLassick , Isabel Mestres , and familar faces from Spaghetti or Paella Western as Luis Prendes , Charly Bravo , Luis Barboo, Rafael Albaicin , Romano Puppo , and Helga Line .
