Four school gamers, Art, Vic, Phil, and Kira, find a strange laptop. The laptop turns out to be a portal to the world of an experimental computer game, "Heroes of Envell". The heroes choose their game classes and start the game; otherwise, they cannot return to the real world. But the first training level already turns into a serious threat.

Art, Vik, Phil, and Kira find weapons from the game "Heroes of Envell" in the real world. Because of Phil's stupidity, classmate Ilya turns into an ice statue. The heroes have to return to the game to charge the weapons and dispel the spell on Ilya. Meanwhile, a mysterious enemy is watching the heroes - an invisible lizard named Salamander. She wants to take the laptop for herself. And only Vik can stop her.

Art, Vic, and Kira are going to return the laptop with the dangerous game, but at the last moment, they agree to use the game's features to help Phil. The heroes do not yet know that Phil is deceiving them: he is going to get a new level to unlock the spell and pass the test with its help. To get a new level, the heroes take on a side quest – harvesting crops on a local farm. But even such a simple task turns into a dangerous adventure when Morgarth's soldiers appear on the farm.

The heroes learn that the game will not hold the villain, Morgarth, and that Morgarth wants to get them into the real world, too. Art tries to explain this to his class and teacher, but is met with a wave of ridicule. A hurt Art opens his laptop to prove his case. The laptop does not work as Art planned. In the game, the heroes and the teacher are waiting for an ambush prepared by Morgart. And this time, victory will not be easy. If the heroes can win at all.

The guys found the key in the game, but the monster cleverly stole it and swallowed it. And thanks to Kira's mistake, he also escaped to the real world. Now the heroes will have to not only return the key and the laptop, which the monster also stole, but also learn the secret of the key and the door.

The heroes go on a school excursion to the Kunstkamera. The salamander lures them into an empty hall and brings the exhibits to life. The heroes have to fight off zombie vegetables, and they heroes are outnumbered. To defeat the monsters, the heroes decide to split up: two go to the game, two guard the laptop. And as luck would have it, the lot to guard falls to Art and Kira. As luck would have it, Art has seriously offended Kira and can't ask for forgiveness.

In the game, Phil finds an artifact – the Box of Greed. The box turns out to be a source of endless gold. Phil is greedy and decides not to share such a treasure with his friends, even though they need gold coins to progress in the game. Phil returns to the real world to get a mountain of gold. However, Phil does not suspect that even for free gold you will have to pay.

Ilya persuades Vik to fix his broken phone – after all, Vik is so kind and can’t refuse when asked for help. To fix things, Vik must upgrade his glove. To upgrade, he needs wood. And how lucky – the heroes have just reached a new location: a huge forest. Kira and Art are against it, but Vik decides to help Ilya in secret from them. Only Vic forgot the main rule in games: never walk through the forest alone.

The Christmas ball is underway. Art and Kira must rehearse a waltz. Kira cannot refuse to participate, otherwise Art will be paired with another girl, and jealous Kira cannot allow this. In the game, her jealousy does not weaken: the mysterious forest archer Val copes with any task better than Kira. Val is a better fighter, a better jumper, and worst of all, a better waltzer. Kira must deal with her jealousy and its consequences.

An unknown monster nicknamed Chupacabra stole Art's sword. In pursuit of Chupacabra, the heroes find themselves in a mysterious place - an island outside the main game. Here, Chupacabra hides inside a strange artifact - a cube that can change the properties of the game. The heroes fail to get Chupacabra, and they take the cube with them to solve a puzzle in class. Meanwhile, it's time for the class to choose a new class monitor. And proud Art can't just pass by when it turns out that they want to choose him instead of Ilya.

Val led the boys to a secret settlement that Morgarth didn't know about yet and introduced them to her people. The heroes were given a pearl that would lead them along a safe path, and they followed it. Vic decided to return to give Val a Valentine, but he was followed by Morgarth's puppets, and they learned about the secret settlement. Morgarth's soldiers have kidnapped all the inhabitants, and now the heroes must free them... or not free them.

Because of Phil, the cube falls into Ilya's hands. But Ilya doesn't know how to use the cube and, by mistake, turns into a monster. Phil is afraid to admit to his friends that because of him, Ilya needs to be saved again. He will have to deal with Monster Ilya alone. Alone in a dark, dark school. Alone in a dark, dark school and without swords and crossbows, you can’t hurt your classmate. Good luck, Phil. You won’t have any other weapons.

At the end of episode 12, the heroes discovered a strange room. It turns out that this is a level editor – a room from which you can control the entire game. Phil sets himself to the maximum level and gets all of his character's skills – yes, absolutely everything. The problem is that Phil doesn't know how to control them. And powerful spells wouldn't hurt - with the help of the level editor, the heroes move straight to Morgart's castle to save the teacher. In the castle, Morgart happily welcomes unexpected guests. Yes, he has the teacher, but Morgart is in no hurry to give her to the heroes. Instead, the villain offers a deal - he agrees to give Marya Stepanovna in exchange for an almighty cheat cube. The fate of the teacher and the entire game world is literally in the hands of the main characters.

The main characters are against the main villain. The long-awaited battle. Only the heroes approached this important moment completely unprepared. And as we know, in games, you can't go to the final battle with unpumped equipment. It's good that Marya Stepanovna is on the side of the heroes - during her captivity, she pumped up her guitar and fighting skills. However, Morgarth is not so simple. He has enough aces up his sleeve to deal with the heroes. The fight promises to be intense.

The cheating cube, the object of Morgarth's attention, is lost. Morgarth is desperately searching for the cube throughout the game. The heroes decide to intercept Morgarth's spies and find the cube first. Meanwhile, the school term is coming to an end, and Kira has a problem: she got a bad grade in geography. Kira hopes that Elena Viktorovna will help her fix the bad grade. After all, Kira's mother threatened to transfer her to another school if she got even one bad grade in the quarter. But Elena Viktorovna refuses to help. Then Kira decides to act on her own. Really, what bad could happen if she slightly improved her grade in the electronic journal?

The heroes have found the place where the cube is hidden. Or rather, they think they have. But to check it out, they need to get to the distant island. Luckily, the heroes have a flying bike. Unfortunately, it needs to be repaired and refueled. While Elena Viktorovna and Vik stay to fix the bike, Art and Phil go to the mine where fuel ore is mined and fuel monsters live. But more terrible than any monsters will be the temptation of power that awaits Phil in the depths of the mine.

The heroes finally reach the island where the cheat cube is hidden. All that's left is to find it. Which isn't easy, because the entire island is one huge garbage dump. While Phil, Vic, and Elena Viktorovna are busy searching, Art decides to return to the real world. After all, it's almost five o'clock, and Art knows that Ilya has a date for five. And it looks like it's going to be a date with Kira.

A small, mischievous monster named Chupacabra offers a deal: exchange Creep for a cube. This is impossible - Kira will never give up her beloved pet, no need to ask. However, it is also impossible to ask Kira, since transferring to a new school, she has not been in touch for a long time. But why? It's time to finally find out what Kira is doing while her friends are looking for the cube.

The greedy Chupacabra demands Creep in exchange for the cube. Of course, Kira will not give up her beloved pet for anything in the world. And the idea to turn Vic into Creep has failed a little. There must be another way to get the cube. The heroes decide to follow the Chupacabra's dwelling. A good plan. The problem is that it takes time, and the heroes don't have it. Because Morgarth knows where the cube is and is already preparing a new attack.

Vic is about to return to the game to save Val. However, it seems that Phil beat him to it: he took the laptop first and locked it in the theater. But the locked door is only the first and easiest obstacle in Vic's path. Ahead of him lies a long and dangerous quest to find the princess. Will Vic cope alone? Will Val wait for him? Has she forgiven Vic's mistake? And the main question - what is Phil doing in the game?

While Vic saves Val, Phil and Kira begin their quest: to bring back the Creep. Phil has just the right spell. Kira and Phil's plan is simple: log in, cast the spell, summon the Creep, and quickly return. But as soon as the heroes return to the game, Phil runs out of mana, and hordes of monsters are hunting Kira. Oh, these simple plans - why are they always so difficult?

Buckwit gives the heroes a quest: remember the password to the cheater's cube and return it to the game. But the heroes never entered any password. Now, Vic, Phil, and Kira are wondering, "What could the code word be?" Meanwhile, the real question they should be asking is, "Can we trust Buckwit?"

To be inside the game forever is very scary. But with a first-person view - very cool! Feel yourself in the game!

Salamander allows Art to use the mirror to communicate with the outside world. However, Art's attempt to ask Ilya for help fails. Moreover, Morgarth regards Salamander's actions as a betrayal and sends an army of puppets to her palace. Now Art and Salamander must survive this attack and protect the mirror - after all, this is their only chance to escape the game.

The heroes have escaped the game. What awaits them in the city, which seems to have been captured by Morgarth for a month?

Will the friends be able to stop Morgarth? What will happen to the city, and will the guys return to the game?
