The title sequence story opens with a space shuttle orbiting the Earth. The bay doors open, releasing a Corvette. An astronaut seated in the car then begins descending through Earth's atmosphere, landing in a desert canyon.
In the framing story, the astronaut Grimaldi arrives at home, where he is greeted by his daughter. He says he has something to show her. When he opens his case, a green, crystalline sphere rises out and melts him. It introduces itself to the terrified girl as "the sum of all evils". Looking into the orb known as the Loc-Nar, the girl sees how it has influenced societies throughout time and space.
Original story by Daniel Goldberg and Len Blum; inspired by Moebius' The Long Tomorrow stories.
In a dystopian New York City in the year 2031, cynical taxicab driver Harry Canyon narrates his day in film-noir-style, grumbling about his fares and occasional robbery attempts, which he thwarts with a disintegrator installed in the back of his seat. He stumbles into an incident where he rescues a girl from a gangster named Rudnick, who had murdered the girl's father. She tells him about her father's discovery: the Loc-Nar, an artifact over which people are killing each other. Harry takes the girl back to his apartment where she climbs into his bed and has sex with him. The next day, one of his fares is Rudnick, who threatens Harry if he does not cooperate. The girl decides to sell the Loc-Nar to Rudnick and split the proceeds with Harry. At the exchange, Rudnick takes the Loc-Nar out of its case and is disintegrated. Meanwhile, the girl informs Harry that she's keeping all the money for herself and pulls a gun on him. Harry is forced to use his disintegrator on her. He keeps all the money and writes it up as a "two-day ride with one hell of a tip".

A nerdy teenager finds a "green meteorite" near his house and puts it in his rock collection. During a lightning experiment, the orb hurls the boy into the world of Neverwhere, where he transforms into a naked, bald-headed muscular man called Den, an acronym for his earth name, David Ellis Norman. After getting a nearby flag around him to keep anyone from seeing his "dork" hanging out, Den witnesses a strange ritual, rescuing a nubile young topless woman who was about to be sacrificed to Uhluhtc. Reaching safety, she introduces herself as Katherine Wells from the British colony of Gibraltar. While she demonstrates her gratitude with sexual favors, they are interrupted by the minions of Ard, an immortal man who wants to obtain the Loc-Nar for himself. He orders Den to get the Loc-Nar from the Queen, who performed the ritual. Den agrees and infiltrates the palace, but is promptly caught by the Queen, who offers leniency if he has sex with her. He complies, thereby distracting the Queen while the raiding party steals the Loc-Nar. Den escapes and races back to rescue Katherine from Ard. Recreating the lightning incident that drew him to Neverwhere, he is able to banish Ard and the Queen. Den's voice-over has him suspecting that they were teleported to his mom's house and she will be surprised. Refusing the opportunity to take the Loc-Nar for himself, Den rides with Katherine into the sunset content to remain in Neverwhere. As for the Loc-Nar, it rises into the sky and lands on a space station where it is picked up by someone.
On a space station, crooked space captain Lincoln F. Sternn is on trial for numerous serious charges presented by the prosecutor consisting of 12 counts of murder on the first degree, 14 counts of armed theft of Federation property, 22 counts of piracy in high space, 18 counts of fraud, 37 counts of rape, . . . and one moving violation. Pleading "not guilty" against the advice of his lawyer Charlie, Sternn explains that he expects to be acquitted because he bribed a witness named Hanover Fiste. Fiste takes the stand upon being called to by the prosecutor, but his perjury is subverted when the Loc-Nar, now the size of a marble, causes him to blurt out highly incriminating statements about Sternn(though whether or not any of them are true is unknown) before changing him into a hulking muscular form that chases Sternn throughout the station, breaking through bulkheads and wreaking havoc. Eventually, he corners Sternn, who gives him his promised payoff, and he promptly shrinks back to his gangly original form. Sternn opens a trap door under Fiste, ejecting him into space. The Loc-Nar enters Earth's atmosphere with Fiste's flaming severed hand still clinging to it.
Because of time constraints, a segment called "Neverwhere Land", which would have connected "Captain Sternn" to "B-17", was cut.
The story follows the influence of the Loc-Nar upon the evolution of a planet, from the Loc-Nar landing in a body of water, influencing the rise of the industrial age, and a world war. This original story was created by Cornelius Cole III.
The original rough animatics are set to a loop of the beginning of Pink Floyd's "Time". The 1996 VHS release included this segment at the end of the tape. On the DVD release, this segment is included as a bonus feature. In both released versions, the sequence is set to the music of "Passacaglia" (from Magnificat), composed and conducted by Krzysztof Penderecki.
A World War II B-17 bomber nicknamed the Pacific Pearl makes a difficult bombing run with heavy damage and casualties. As the bomber limps home, the co-pilot goes back to check on the crew. Finding nothing but dead bodies, he notices the Loc-Nar trailing the plane. Informing the pilot, he heads back to the cockpit, when the Loc-Nar rams itself into the plane and reanimates the dead crew members as zombies. The co-pilot is killed, while the pilot parachutes away in time. He lands on an island where he finds a graveyard of airplanes from various times, along with the wrecked airplanes' zombified airmen, who surround him, sealing the horrified pilot's fate.

So Beautiful and So Dangerous
Dr. Anrak, a prominent scientist, arrives at the Pentagon for a meeting regarding mysterious mutations that are plaguing the United States. At the meeting, the doctor tries to dismiss the occurrences. When he sees the Loc-Nar in the locket of Gloria, a beautiful buxom stenographer, he behaves erratically and attempts to sexually assault her. A colossal starship drills through the roof and abducts the doctor and, by accident, Gloria. The ship's robot is irritated at Anrak, who is actually a malfunctioning android, but its mood changes when it sees Gloria. With the help of the ship's alien pilot and co-pilot Edsel and Zeke, the robot convinces Gloria to stay on board and have "robot sex"(albeit off-screen). Meanwhile, Edsel and Zeke snort a massive amount of a powdered drug called Plutonian Nyborg before flying home, zoning out on the cosmos. Too intoxicated to fly straight, they crash land unharmed in a huge space station.
Original story by Daniel Goldberg and Len Blum; inspired by Moebius' Arzach stories.
The Loc-Nar, now the size of a giant meteor, crashes into a volcano on an unnamed world, changing a tribe of human outcasts into mutated barbarians who ravage a peaceful city. The elders desperately try to summon the last of a warrior race, the Taarakians. Taarna, a strong, beautiful, and mute Taarakian warrior maiden, arrives too late to stop the massacre and resolves to avenge the city(In her defense, the elders of the city did wait until the enemy was literally about to ram their way into the elders' temple, so she really never had a chance of saving anyone there, anyway.). Her search leads to the barbarians' stronghold, where she is captured, stripped of her clothing, tormented and left for dead. With the help of her Taarakian mount, she escapes, places her outfit back on, and confronts the barbarian leader. Though wounded, she defeats him. With Taarna readying her final attack on the Loc-Nar, it tells her not to sacrifice herself as she cannot destroy it. She does not relent, and her self-sacrifice destroys the Loc-Nar.

As the final story ends, the Loc-Nar terrorizing the girl is similarly destroyed, blowing the mansion to pieces. Taarna's reborn mount appears outside and the girl happily flies away on it. It is then revealed that Taarna's soul has been reincarnated in the girl. The girl's hair color changes to that of Taarna and she reveals a Taarakian mark on her neck.
