Santo's son has to fight a secret group of aliens who have lived beneath Earth's surface for some time after he figures out that his friend, The Blue Panther, is being mind controlled by them somehow. While the actions of the son doesn't tarnish the memories of old Santos movies, this movie was still pretty band and can't really hold a candle to the movies that the original Santo appeared in. Also the special effects are extremely lackluster and are relied on a bit too heavily.
DVD Extras: Deleted scenes; Outtakes; Premiere footage; Special effects of; Director Interview; 'the Best of El Santo'; and a Santo Vs. Blue Demon wrestling bout (all in Mexican with NO sub-titles); Also trailers for various crappy Rise Above reality fare .
