This classic Greek tale of a friendship that overcomes even death makes for an interesting sword-and-sandal saga, with Guy Williams in the role of Damon. An apt choice since Williams is himself an expert swordsman, as partially demonstrated in his role as Zorro on American television (1957-59). Pythias (Don Burnett) has been caught plotting the assassination of King Dionysis I of Syracuse (Arnoldo Foa). Before his execution, Dionysis grants Pythias leave to put his affairs in order because Damon volunteers to stand in his stead if Pythias does not come back to face the executioner. Damon's act is considered foolish. He was safe, why should Pythias come back? But the two are devotees of the Pythagorean mysteries, and their faith in brotherly love goes beyond self-interest. When Pythias does return in the allotted time, King Dionysis is impressed enough to have a change of heart.
