Marcellus, a young Roman officer, has been exiled. In Jerusalem, it becomes his duty to crucify a Galilean. Although he believes the man innocent, he obeys. He also tosses dice for the simple homespun robe which the Galilean wore. He wins but becomes a desperately troubled man, restless and obsessed with thoughts of the Galilean and the persecuted Christians. Marcellus turns more and more to the Galilean but hesitates to accept Him as divine until, in a final scene of emotion and power, he accepts death for himself and his young wife rather than renounce his faith.
