As Wallace and Gromit relax at home, wondering where to go on vacation during the upcoming bank holiday, Wallace decides to fix a snack of tea and crackers with cheese. Finding no cheese in the kitchen, he decides that the pair should go to a place known for its cheese. A glance out the window at the night sky gives them the idea to travel to the moon, since, according to Wallace, "everybody knows the moon's made of cheese."

The film follows the adventures of Murat (Arkın) and Ali (Akkaya), whose spaceships crash on a desert planet following a battle, shown by using footage from Star Wars as well as Soviet and American space program newsreel clips. While hiking across the desert, they speculate that the planet is inhabited only by women. Ali does his wolf whistle, which he uses on attractive women. However, he blows the wrong whistle and they are attacked by skeletons on horseback, which they defeat in hand-to-hand combat. The main villain soon shows up and captures the heroes, bringing them to his gladiatorial arena so they can fight. The villain tells them he is actually from Earth and is a 1,000-year-old wizard. He tried to defeat Earth, but was always repelled by a shield of concentrated human brain molecules, which looks like the Death Star from Star Wars. The only way he can bypass this impenetrable defense is to use a human brain against it. The heroes escape and hide in a cave full of refugees who already fled the villain's tyrannical rule. Murat develops a romantic connection with the only woman there (Uçar), who looks after the children. (The romance is shown through many long eye-contacts and smiles from the girl, but nothing more.) Zombies of the dark lord attack the cave and turn several of the children into zombies, their blood used to renew the evil wizard's immortality. The three then flee the cave and find a local bar, lifted directly from Star Wars (the Mos Eisley Cantina). The two men quickly get into a bar brawl, but the villain suddenly appears and captures them again.
