Our heroes wind up on the moon when they accidentally wander aboard a rocket ship that their neighbor built in his backyard. Seriously. Once they arrive, they are faced with the terrifying prospect of what to do once their oxygen runs out...but then it turns out that you can actually breathe just fine on the moon. There's also a race of lonely women, backstabbing, betrayal, and a giant spider which will chill you to your core (assuming that you are terrified of children's toys.) For an intergalactic journey this cheesy, there are no better stowaways to help out with a hilarious running commentary than Mike Nelson, Kevin Murphy and Bill Corbett of RiffTrax.com and Mystery Science Theater 3000!
