Judas, whose real name is Alan Scott, used to be a bandit, but after his girl-friend Vivien's death during a robbery in which he took part, he delivered himself and his cronies to justice (thereby earning himself the epithet of Judas). After serving his time in jail, he joins the Pinkerton agency to fight against delinquency. He longs to redeem himself and compensate for the wrongs he committed in the past, because he is sorely tormented by the memory of Vivien and is constantly plagued by the name he has been branded with, which forces him to life a life of loneliness and hatred in which even his colleagues shun him. This series aimed to offer a presentation in the by now classical "giant" format, reviving stylemes and themes already well tested in the popular weeklies of the preceding years, especially since the Italian western was enjoying a great vogue at that time. But despite the good scripts by Ennio Missaglia and the well-drawn illustrations by his brother Vladimiro and by the talented hand of Ivo Pavone, this series was not favorably received by the reading public, and closed after sixteen issues.
