On an assignment to investigate a crater, two dimwitted soldiers (Bob Ball and Frankie Ray) stumble upon a scary plant-link creature. Upon following the VegeMonster into a cave, the bumbling buddies are taken prisoner by two beautiful women who have come from outer space to take over Earth. Soon, the not-so-dynamic duo discover the alien vixens lacking in the love department...and think they might've found a way to save the planet!
