synopsis:
Aliens have come to earth. Believing that the people of Earth have captured their beloved princess, the aliens ask for her return or they will destroy the Earth. Wonder Woman decides to go searching for the missing royal despite not knowing what she looks like. Meanwhile, Steve Trevor -- in a trance like state -- is flying her plane away, being drawn by some mysterious force. Wonder Woman follows through and learns that her love is being attracted by a strange woman who has a flute. Apparently, Steve is under this woman's spell and does not know who Wonder Woman is. The strange woman manages to paralyze Diana with some sort of strange ray and lures Steve away. Meanwhile, with the 24 hour time limit from the aliens to Earth draws near.
Wonder Woman caught up later and deduces that the woman who has stolen Steve is really the alien princess. She explains to the princess that her people have threatened the Earth and that she has to return to the flying saucers. The princess however refuses to do so. The princess explains that she is not a single ruler of her world, but one of thousands of princesses (She being the 1003rd one herself). Craving to be worshiped as an individual, she fled her world and sought worship on the planet Earth.
Wonder Woman challenges the princess to a competition to see who is more superior. Wonder Woman won the challenge and the princess is forced to walk the "black rocks" on a nearby river where crocodiles await to attack her. Wonder Woman saves her life. She agrees to return to her home planet and spare the Earth, but she is taking Steve Trevor with him.  However, when the flying saucers arrive to pick her up, their transport beam reveals her true form: that of a robot. That causes Steve to snap out of her control and abandon her. Wonder Woman advise the aliens to handle rulership properly.
