El Topo

El Topo is traveling through a desert on horseback with his naked young son, Hijo. They come across a town whose inhabitants have been slaughtered, and El Topo hunts down and kills the perpetrators and their leader, a fat balding Colonel. El Topo abandons his son to the monks of the settlement's mission and rides off with a woman whom the Colonel had kept as a slave. El Topo names the woman Mara, and she convinces him to defeat four great gun masters to become the greatest gunman in the land. Each gun master represents a particular religion or philosophy, and El Topo learns from each of them before instigating a duel. El Topo is victorious each time, not through superior skill but through trickery or luck.
