"Guest from the Future:
A Film Screenplay" by Kir Bulychev, summary Automatic translate

The children’s science fiction film’s script was created in 1983, based on the novella "One Hundred Years Ahead." This sci-fi story was soon successfully adapted into a film. The television series gained nationwide fame, and the leading actors became true youth icons. An interesting detail is the abundance of unique scenes that were not included in the final film version, such as the appearance of an eccentric magician and the visual metamorphoses in the hospital.

Journey to the Future

Schoolchildren Kolya Gerasimov and Fima Korolev observe a mysterious woman on a Moscow street. Kolya secretly follows her to an abandoned, vacated building. In the basement, the boy discovers a time capsule hidden behind a brick wall. Curiosity gets the better of him, Kolya presses the buttons on the remote control and accidentally triggers a space-time transfer.

The hero is transported to April 2084. There, he meets the android Werther, a melancholic cleaning robot at the Institute of Time who secretly writes poetry. Werther conducts an inventory of the alien from the past, but succumbs to persuasion and allows Kolya to go on a tour. Entering a park of the future, the boy sees antigravity transport, talks with a centenarian named Pavel, and encounters aliens from Alpha Centauri. Wanting to see interplanetary ships, Kolya boards a floating bubble and heads to the spaceport.

Myelophone theft

In the spaceport’s cargo terminal, a boy notices strange activity. Two stowaways emerge from a container arriving from the asteroid belt. They are the ruthless space pirates Krys and Veselchak U. The villains infiltrate the waiting room, where the cosmonauts are met by Professor Seleznev and Old Man Pavel. The pirates stun Old Man Pavel with a paralyzing ray. Veselchak U instantly transforms into the old man.

Under cover of disguise, the villains extract information about the myelophone from Professor Seleznev. This unique device is designed to read the thoughts of living beings. The device is located at the Space Zoo, where Alisa Selezneva uses it to study rare animals. Having learned the location, the pirates head to Cosmozo. Kolya unsuccessfully attempts to warn others of the danger and then gives chase to the criminals.

At the Space Zoo, the boy finds the staff tied up — a real attendant and a talking green goat. After removing the gags and untying the ropes, Kolya discovers a devious plan. At that moment, the fake attendant and the fake goat track down Alice. The villains snatch the girl’s myelophone and push her into the pond.

A rapid pursuit ensues. The green goat selflessly throws itself at the feet of the fleeing Merry U. The massive pirate falls to the ground with a crash. Kolya picks up the dropped myelophone and flees. Returning to the Institute of Time, he asks Werther for help.

The android shelters the boy in a time capsule and sacrifices itself to preserve chronological order. Blaster shots destroy the noble robot. Kolya manages to travel back to the twentieth century. The pirates hack the remote control and travel after him. Rescued by the dolphin, Alice learns the boy’s coordinates from the green goat and also travels back in time.

Searches in the twentieth century

Kolya returns to Moscow in 1984 and safely hides the myelophone in his home. Meanwhile, the pirates roam the streets, searching in vain for the fugitive. While pursuing the villains, Alisa is hit by a car and ends up in the hospital. She feigns amnesia to avoid unnecessary questions. In the hospital, she meets Yulia Gribkova. A striking coincidence emerges: Yulia is in sixth grade at School No. 26, the same school where Kolya is enrolled.

Alien villains track down Alisa’s location. They infiltrate the hospital disguised as a medical worker and a fake father. Their disguises give them away: one of the pirates is wearing two right shoes. The girls fight their way out of the ward, causing a commotion. They escape through a first-floor window and hide in Yulia’s apartment.

The denouement of the school intrigue

Social integration continues. Alisa enters Form 6B disguised as a new student. She must identify the right person, as there are three boys named Kolya in the class — Sulima, Sadovsky, and Gerasimov. The visitor from the future impresses the teachers with her impeccable pronunciation in English class and her phenomenal athletic achievements on the track.

The pirates organize surveillance of the school, disguised as random passersby. Kolya Gerasimov, unable to withstand the psychological strain, reveals the secret to his friend Fima Korolev. Soon, the villains trick Kolya and capture him. They hide the bound student in the basement of the same abandoned house.

Alisa and her perceptive classmates analyze the facts and unravel the kidnappers’ plan. The children rush en masse to their friend’s rescue. A tense confrontation ensues in the empty house. Kolya stoically refuses to hand over the myelophone, despite threats of gunfire. The students surround the villains, creating a numerical advantage. Alisa manages to seize the device.

Veselchak U and Krys activate their blasters and attempt to burn through the brick wall to escape. At this critical moment, the door to the time chamber opens. Lucretia, an operative at the Institute of Time, appears on the threshold. She creates an impenetrable protective field. She calmly approaches the firing pirates and sternly announces, "In the name of galactic law, you are under arrest."

The pirates are neutralized, the danger has passed. The children gather around the visitor from the future. The girl says goodbye to her new friends and encourages her classmates, confidently predicting outstanding professional achievements for them. Alice enters the time capsule. The wall closes, and the girl dissolves into a shining light, returning forever to her own era.
