The main problem with the film is that it takes too long to get going, the actual meeting and battle between the robot and mummy is right at the very end (and isn't the most amazing battle in movie history if we are to be honest though is mercifully short). The film is slow because it includes a recap from the two previous mummy films in the series so at least you can save time by just watching this one and not the others i guess.
As to the film plot, the mummy Popoca (Angelo de Steffani) is guarding ancient treasure which mad (of course) scientist Dr Krupp (Luis Aceves Castañeda) wants for himself. As the mummy usually kills all who try and steal the treasure Krupp builds a cyborg robot (Adolfo Rojas) to destroy the mummy. Then he plans to use the loot to build an army of similar robots and conquer the world. Though if we are to be honest i suspect the world's armed forces would have the ability to defeat an army of robots that move incredibly awkwardly and slowly.
Like the robot the film isn't very good, the best part of the film is the title. However it is worth watching once just for that.
