The film is presented as an anthology of short horror films, built into a frame narrative which acts as its own short horror film. Each short film is linked together with the concept of found footage (each segment is from the VHS tapes found in the first film).
The film is set in an alternate-reality Earth. In 1899, The Martians launched an unprovoked attack on the major nations of the world. In Leeds, England, a younger Eric Wells watches in horror as a Martian Tripod lays waste to his city and then kills his father and mother. But before it can kill him, the Martian Tripod suddenly keels forward and crashes into the ground. Over 140 million people were killed by the Martians, and many of the great cities of the world were destroyed until the Martians were killed off by Earth's bacteria, against which the Martians had no defence.
Bea (Rose Leslie) and Paul (Harry Treadaway) are newly married and off to have a romantic honeymoon in a rustic cabin set in a secluded forest. During their stay there, they go to a small restaurant whose owner initially acts hostile and asks them to leave, but later calms down, realizing he was Bea's childhood friend, Will. Will's wife then comes in, acting strangely and saying they need to get away. Afterwards, everything goes normally until their wedded bliss is cut short when Bea goes missing. Paul finds her naked and disoriented in the woods with no evidence as to how she got there or why she was there in the first place. He takes her back to the cabin, where she claims she was sleepwalking due to stress, and tells him to make nothing of it.
The film tells the story of a young female (Birve) that was sent from the planet Epsilon to judge how humans have managed the planet. She crash lands naked in a desert, but is found by a surveyor (Brisbane) who gives her some clothes. She informs the surveyor that other alien races consider humans to be failures that suffer from carelessness and greed. She has the ability to transport herself and the surveyor instantly to any location, and she uses this to demonstrate her point. Eventually the two fall in love.

At the funeral of an Old Man's wife, mourners are gathered by an open grave, among them her husband (Bela Lugosi). Overhead, an airliner is heading towards Burbank, California. The pilot Jeff Trent (Gregory Walcott) and his co-pilot Danny (David De Mering) are blinded by a bright light and loud sound. They look outside and see a flying saucer. The pilots follow the saucer's flight until it lands at the graveyard, where the funeral's gravediggers are killed by a female zombie (Maila Nurmi).
The story begins in 1957 in the star-filled skies above California's Mojave Desert. It is a special night for noted astronomer Ted Lewis, who is preparing a special anniversary dinner with steaks for his beautiful, adoring wife Lana while observing the annual meteor shower of the Perseids. In another part of town, Tammy, a waitress at small local diner with big plans for the future, looks out her window and is excited to see a shooting star, which she takes as a good sign for her dreams.
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. Anderson agrees to help the creature and even intends to allow it to assimilate his wife (Beverly Garland) and friend Dr. Nelson (Peter Graves).

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.
The film starts out with Captain Gantu on his new spaceship (his original got destroyed in the first film), being hired by Hämsterviel to retrieve the experiments.
As Prof. Bernard Quatermass (Brian Donlevy) struggles to gain government support for his Moon colonisation project, his interest becomes focused on reports of hundreds of meteorites landing in Winnerden Flats. Travelling there with Marsh, his colleague (Bryan Forbes), Quatermass finds a huge complex under construction, based on his lunar colony plans. Marsh discovers that an undamaged meteorite is shaped like a small stone rocket. It then cracks open, releasing a gas, leaving him with an odd V-shaped mark on his face. Black-clad guards from the complex arrive, armed with machine guns and sporting similar V-shaped marks, and take Marsh away, knocking down Quatermass and ordering him away.
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.
