La Marca del Zorrillo

In California in 1840, the cross-eyed Viscount of Texmelucan offers a party to receive his son Tin, who returns from Italy where he was studying. The young man turns out to be a coward who fled in terror after refusing to fight in mourning with Captain Gaspar. In his escape, Tin rescues a witch who gives him an ointment that will make him invincible for an hour. The cowardly swordsman will have three opportunities to use him and save his father from the injustices of the evil governor Marcelo. (cinemexicano.mty.itesm.mx)
