Man (and woman) finally makes it to the moon and finds a dying race of leotard clad beatnik feminists bent on invading Earth and conquering everyone through seduction, mind control and teleportation.
Bonus points for interpretive dance and jazz flute music.
Forget all that one giant leap for mankind nonsense, we have lithe, somewhat half-Vulcan women prancing about and scheming to take over Earth. The only thing in their way is a team of manly men and one pretty awesome woman and two giant spiders that are controlled by fishing line.
Peril abounds on the moon!
All hail our Cat Woman overlords!
