Pedro Penduko steals a legendary talisman called the Cuatro Vidas from a collector named Abraham.
Pedro, with his modern clothes and equipment, causes a stir in town, especially when Kidlat's niece Anna, to whom he becomes infatuated with, connects his arrival with that of a prophesied savior that will defeat Losipero, the demon leader of a group of monsters that has been harassing the town and abducting residents.
Abraham arrives and helps Pedro defeat the monsters by using a barbell that turns Abraham into Captain Barbell and giving Anna a white stone that turns her into Darna.
Pedro chases Losipero with the help of Flavio until he corners the demon and places the Cuatro Vidas around his neck, killing him.
As Pedro patches things up by kissing Bambi, Losipero suddenly appears, only for police officers to arrest him, saying that he is actually a lunatic named Don Robert.
