Dr. Tom Anderson (Lee Van Cleef), an embittered scientist, has made contact with Zontar, a Venusian creature, while using his radio transmitter. The alien's secret motivation is to take complete control of the Earth by enslaving humanity using mind control devices; the alien claims it only wants to bring peace to our troubled world by eliminating all emotions.

The year is 1980, and the film opens with the launch of the JX-1 Hayabusa spaceship into outer space. The ship, originally sent to collect data on Saturn, has its course diverted to investigate the mysterious star Gorath, reported as being 6000 times the size of the Earth. It is feared that the star's path could come dangerously close to Earth. The JX-1 reaches locates Gorath and it's much smaller than earth but with 6000 times the gravity. The JX-1 radio's back any data about the star but gets sucked into the star's gravitational field which drags the ship into Gorath, incinerating it.
Astronaut Capt. Richmond Talbot inadvertently volunteers to make the first manned flight around the moon. He is ordered to keep the upcoming moon flight a secret, even from his family. Due to the classified nature of the mission, he is placed under the watchful eye of several national security agencies.
Financial disaster looms for Grand Fenwick when the current vintage of its only export, wine, starts exploding in would-be consumers' faces. Prime Minister Mountjoy (Ron Moody) decides to ask the United States for a loan, ostensibly to fund its entry in the race to the Moon, but actually to save the duchy (and install modern plumbing so he can have a hot bath). The devious politician knows that the Americans will not believe him, but will consider the half million dollars he is asking for to be cheap propaganda supporting their hollow call for international co-operation in space. He is delighted when they send him double the amount as an outright gift. The Soviets, not wishing to be one-upped by their Cold War rivals, deliver an obsolete rocket. Mountjoy asks resident scientist Professor Kokintz (David Kosoff) to arrange a small explosion during the "launch" of their lunar rocket to make it look like they have actually spent the money as intended.
The story involves the people of Mars, including Momar ("Mom Martian") and Kimar ("King Martian"). They're worried that their children Girmar ("Girl Martian") and Bomar ("Boy Martian") are watching too much Earth television, most notably station KID-TV's interview with Santa Claus in his workshop at the North Pole. Consulting the ancient 800-year-old Martian sage Chochem (a Yiddish word meaning "genius"), they are advised that the children of Mars are growing distracted due to the society's overly rigid structure; from infancy, all their education is fed into their brains through machines and they are not allowed individuality or freedom of thought.
Dr. Who (Cushing) and his granddaughters, Susan (Tovey) and Barbara (Linden), show Barbara's boyfriend Ian (Castle) the Doctor's latest invention, a time machine called TARDIS. When Ian accidentally activates the machine it transports them to a petrified jungle on a world devastated by an ancient nuclear war, fought between the Daleks and the Thals. (Although the planet is not named in the film, in its sequel it is retroactively revealed to be called Skaro, matching the name given in the television series.) At the conclusion of the war the Daleks, heavily mutated by radiation, encased themselves in protective machines and retreated into their city. The humanoid Thals survived the fallout through the use of an anti-radiation drug and became a peaceful race of farmers. The Thals' crops have recently failed, however, and they have journeyed to the petrified jungle to seek help from their former enemies. The Daleks, while determined to become the dominant race on the planet, are unable to leave the city due to their vulnerability to radiation and reliance on static electricity to power their travel machines.

Batman (Clark Bartram) corners an escaped Joker (Andrew Koenig), only to have the villain suddenly dragged off by an Alien. The Alien is, in turn, killed by a Predator, which Batman fights and defeats. Other Predators then appear just as more Aliens emerge from the darkness behind Batman. The film ends abruptly with Batman caught in between the two alien species.
Two huge interplanetary ships on an expedition into deep uncharted space receive a distress signal emanating from Aura, an unexplored planet. Both ships, the Galliott and the Argos, attempt to land on the surface of the fog-encased world. While entering the planet's atmosphere, the crew of the Argos becomes possessed by an unknown force and try to violently kill each other. Only Captain Markary (Sullivan) has the will to resist, and is able to force all of the others aboard his ship out of their hypnotic, murderous state.
