Careening towards Earth, a Martian saucer filled with, you guessed it, Martians, in this case shirtless men in tight silver pants with long blond locks, is carrying a foreboding message-stop developing atomic bombs or we'll turn this into that other movie, The Day the Earth Stood Still. Earth responds with general guffaws, and so the Martians land in a sports arena in Mexico City and start vaporizing fans with their superpowerful “Astral Eye.” Big mistake: Santo, the Man with the Silver Mask, happens to be en la casa, and he doesn't like his followers being turned into carbon dust. A wrestling match ensues in which the Martians almost succumb, but then they dematerialize via their teleportation belts. The fate of the world hangs in the balance and no one is steadier on his feet than Santo. And like any great brawler, Santo is gonna take the fight to their corner . . . of the universe.
