A psychiatrist uses his wife's hypnotically recovered memories of a past life as an Aztec princess to discover a hidden tomb with treasures... but they come with a curse.
And a mad scientist has a plan to overcome the curse and steal the treasure to fund his evil masterplan.
I chose this at random, cuz with a title like that, how could I resist! I did not know:
it was the third film in a trilogy
it recapped and recycled much of the first two films, which would explain why 80% seems like retelling and flashbacks.
Despite being a brief 64 minutes, it still feels like this could have been cut another 20 minutes, and the promised "robot"-(more like a cyborg)-on-mummy action was only a few minutes at the very end.
I didn't see the previous movies so I kind of liked the Aztec parts and wished there was more of that. The villain scientist was doing his best. The robot was fun in a campy way. But mostly it was pretty tedious.
