We discover that we’re going to the moon to rescue the Moon-people in Cat-Women of the Moon (1953), who have deviously influenced the lady navigator of the first ship to go to the moon. There’s some barriers, of course, such as the moon-spiders (I think my parents made one just like those in the movie to scare the kids on Halloween and called it Herbie), and the fact the ladies on the moon, having eliminated the men of their race, plan to do the same with Earth-men.
And it’ll be a takeover, not a rescue.
It’s all dull, corny stuff, and if there was a noteworthy theme, it escaped my attention. In fact, we both managed to fall asleep during it. Stay away from this dog.
