Scientists Dr. Erik von Steiner (Preston Foster), Dr. Steve Connors (Philip Carey) and Carol White (Merry Anders) are testing their time viewing device, drawing enormous amounts of power. Danny McKee (Franken), a technician from the power plant, has been sent to tell them to shut down their experiment. During the test, odd shadows quickly cross the room before the screen shows a stark, barren landscape. Danny discovers the screen has become a portal and steps through.
A man (Davos Hanich) is a prisoner in the aftermath of World War III in post-apocalyptic Paris where survivors live underground in the Palais de Chaillot galleries. Scientists research time travel, hoping to send test subjects to different time periods "to call past and future to the rescue of the present". They have difficulty finding subjects who can mentally withstand the shock of time travel. The scientists eventually settle upon the prisoner; his key to the past is a vague but obsessive memory from his pre-war childhood of a woman (Hélène Chatelain) he had seen on the observation platform ("the jetty") at Orly Airport shortly before witnessing a startling incident there. He had not understood exactly what happened but knew he had seen a man die.

A boy, Jimmy Warren, living along the coast in Massachusetts is upset with the unfairness of "modern" life in 1960 when his father scolds him about his school grades. He plays on a wrecked ship along the shore with Kathy. He picks up an odd jar, and wishes he were back in the olden days, on a pirate ship. When Jimmy utters "Where am I?", the magic jar pops open, and a strange little man pops out. He introduces himself as Abu the Genie, and states that he has granted Jimmy his fondest wish: to be on a real pirate ship. Jimmy scoffs at the notion, but Abu insists that they are at that very moment passengers on Queen Anne's Revenge, the ship of the notorious Blackbeard.
In March 1957, Commander Dr. Eldon Galbraithe (Nelson Leigh), engineer Henry Jaffe (Christopher Dark), radioman Herbert Ellis (Rod Taylor) and scientist John Borden (Hugh Marlowe), are returning to Earth from the first spaceflight, a reconnaissance trip around Mars. Suddenly, their spaceship is somehow accelerated to incredible velocities, and they are knocked unconscious. Their ship crash lands on a snow-covered mountain. When they venture out, they discover that they have become victims of time dilation and are now in Earth's future.
The story involves four teenage comrades who take a rowboat along a "river of time" that flows into a mysterious cave and emerges on the other side onto a strange, primeval landscape. The boy actors were Josef Lukáš (Petr, the main narrator), Petr Herrmann (Toník, who also narrates in part), Zdeněk Husták (Jenda), and Vladimír Bejval (Jirka). As they make their way upstream, they realise that they are travelling progressively farther back in time, and facing various perils as they do so (but learning much about prehistoric life in the process). The animals depicted in Cesta do pravěku were never shown interacting with animals of other periods and it is assumed that different parts of the river represented distinct time periods. The plot is somewhat similar to that of the novel Plutonia (1915) by the Russian palaeontologist Vladimir Obruchev, in which a team of Russian explorers enter the Earth's crust via an Arctic portal (a huge depression in the Earth surface created many millions of years previously by the impact of a giant asteroid, into which prehistoric animals had entered), and follow a river that leads them through a sequence of past geological eras and associated animal life. Some scenes in Cesta do pravěku recall Arthur Conan Doyle's 1912 novel The Lost World, with four male protagonists exploring a prehistoric world where they find evidence of native human habitation, are attacked by a group of enraged pterodactyls, witness a twilight fight between a carnivorous dinosaur and a herbivorous one, encounter a Stegosaurus up-close, and see one of their members (Petr) pursued by a Phorusrhacos.
Americans Tommy Albright (Gene Kelly) and Jeff Douglas (Van Johnson) are on a hunting trip in Scotland and become lost in the woodlands. They happen upon Brigadoon, a miraculously blessed village that rises out of the mists every hundred years for only a day. (This was done so that the village would never be changed or destroyed by the outside world.) If any villager ever leaves Brigadoon, the spell will be broken and the village will vanish forever, and any outsider who wishes to stay must love someone in the village strongly enough to accept the loss of everything he or she knew in the outside world. Tommy falls in love with village lass Fiona Campbell (Cyd Charisse), whose younger sister Jean (Virginia Bosler), is about to be married to Charlie Dalrymple (Jimmy Thompson). When Tommy and Jeff happen upon clues about the village and its people that make no sense, Fiona takes them to see Mr. Lundie, the village schoolmaster, who tells them the story of Brigadoon and the miracle. That evening, Mr. Lundie officiates at the wedding of Jean and Charlie, which Tommy and Fiona attend. Interrupting the wedding, the jealous Harry Beaton (Hugh Laing) announces he is leaving Brigadoon to make everything disappear, since the girl he loves, Jean, is marrying another man. Harry's words cause mass chaos among the townspeople and they all rush to stop him. Harry almost crosses the bridge but is stopped short by Tommy, who is knocked unconscious. With men closing in on him, Harry climbs up a tree to hide but is soon shot accidentally by Jeff, who skipped the wedding to hunt and shot at a bird that flew by Harry. Harry falls dead to the ground and is soon found by the men. Fiona frantically searches to find Tommy. Confessing their love for each other, they decide to marry, allowing Tommy to stay in Brigadoon for good. But while Fiona goes off to find Mr. Lundie, Tommy tells Jeff about his plan. Jeff, drunk and remorseful of accidentally killing Harry, tells Tommy he can't just leave everything in the real world behind for this girl he's only known a day. Fiona returns with Mr. Lundie, but Tommy confesses that he cannot stay. Fiona says she understands but is heartbroken and they say good-bye before Brigadoon completely disappears. Tommy and Jeff cross the bridge and walk away.

When Trabbi wakes up he is greatly distressed by the visions and eager to change his life, starting with that very same Christmas Day.

Scrooge tells two other men of business that he has no intention of celebrating Christmas. He refuses leniency to a debtor who owes Scrooge money. Back at his place of business, Scrooge refuses a donation to two men collecting for the poor, suggesting that prisons and workhouses are sufficient for maintaining the poor, and that those who won't go would be better off dead. Scrooge's nephew, Fred (Brian Worth), invites Scrooge to dinner the next day, but Scrooge refuses, disparaging Fred for having married.
