Far away in a little house by the railroad lives a little and a very restless girl called Masha. She loves to play so much that all other animals don't share her enthusiasm and always hide from her. One day she is fed up with it and flees into the forest. There she finds a cozy-looking house that belongs to the Bear, who at this moment just gone fishing. Upon his return, he discovers his lovely house in shambles. He finds the source of the mess inside his very house - it turns out to be a little girl that was using his bed as her personal trampoline. The Bear does his best to get rid of the pesky guest. But when he succeeds, he suddenly feels anxiety for the little child he left in the forest. The Bear rushes to find her and finally discovers her in his own house.

The autumn has arrived. The Bear prepares for his winter bedtime by barricading himself from Masha inside the house. But the little girl manages to find her way indoors and causes yet another mess by awakening a whole swarm of bees. But all her games eventually stop and when the Bear cooks some porridge to feed the child, he discovers her fallen asleep.

The Bear adores New Year’s Eve so much that he wakes up just to celebrate this holiday. He cleans his house, decorates the Christmas tree and waits for the Father Frost to come. But Masha arrives instead and the holiday turns into a disaster: the tree burns down, the decorations break and Father Frost gets into a car accident. The forest inhabitants can be left without presents. But Masha and the Bear do their best to fix the situation and they celebrate New Year like never before.

The Bear wakes up with the arrival of spring. While running around the forest, he stumbles upon a beautiful female bear. He quickly falls in love. He grabs some flowers and chocolates and rushes to her hoping to invite her for a date. Of course, Masha ruins all of his plans. The Bear does his best to get rid of the girl disturbs their idyll. Finally the female Bear notices her and demands an explanation. He tries to explain but faces with a choice – Masha or the female Bear. The Bear can't make up his mind at once and the Female Bear goes away with another bear.

The Bear goes fishing. In anticipation he slings his fishing rod but as soon as the first fish swallows the bait, Masha appears and transforms a pleasant fishing trip into a nightmare. The Bear makes a fishing rod for Masha as well in order to entertain her and she immediately catches the Goldfish.

First snow falls and the Bear decides to teach Masha how to distinguish the tracks of different animals. Masha is quite far from being a good student and brings the poor Bear almost to madness. But to his great surprise it turns out that some of her answers were not as absurd as they seemed.

The Wolves that live in the forest come with a plan to kidnap Masha and demand the Bear to pay a ransom. However the Bear is pleased to find Masha gone and he does not rush the events. Meanwhile Masha turns the Wolves' lives into a hell and they end up paying the ransom to the Bear just to get rid of her once and for all.

A funny interpretation of an old fable about a boy who called for help and shouted “Wolves!” The Bear wants to watch a soccer game but first he needs to get rid of the girl. The Bear sends her foe a walk to the forest and gave her a cellphone in order to be safe. As a result Masha annoys him with her calls for any trivial reasons and when she finds herself in real danger, the Bear doesn’t answer the phone.

The Bear decides to harvest berries and to cook jam. This idea is literally up to Masha’s taste. She tries everything. Afterwards she decides to play an astronaut by putting a glass jar on her head. The Bear tries to get her head out of the container and eventually he succeeds only to discover his own paw inside the same jar. He spends the remaining day in attempts to free his hand.

Masha wants to learn ice skating. But there's nobody around to teach her because the Bear had fallen asleep. However this does not confuse Masha at all. She puts rolling skates on his feet and rolls him out towards the frozen pond where he eventually wakes up. Now he has no choice but to teach the impatient girl how to ice skate.

With the beginning of September, Masha, like all the children wants to go to school and asks the Bear to make her one. Overwhelmed with enthusiasm, the Bear completes the task and the next day Masha sits at a brand new desk and tries to act as an attentive student but ends up bringing the Bear to absolute madness.

The Bear patiently waits to collect the harvest of carrots. And so does the hungry hare. The Bear comes up with an apparently brilliant solution - to make Masha chase the pesky hare away from his garden. But his plan works out in a completely different way.

Masha wants to play hide and seek. But the Bear has other plans in mind. Knowing that it is impossible to go against her wishes, he agrees to play with her. Like many little children Masha “hides” by simply covering her eyes with her hands and the Bear decides to hide himself. He chooses the most incredible places. But nevertheless Masha finds him every time and demands to play with her and once again hides by covering up her eyes.

The Bear wakes up in his chair with an enormous bump on his head and a biathlon cup. But he can't remember how it all happened. Masha and the hare stand beside him with guilty looks on their faces. They tell their interpretations of the story. The Bear has to decide which one is true and which is false.

Tired from Masha's endless games, the Bear pretends to be sick so the little girl would leave him alone. But the caring girl sets to cure her friend. After a series of failed attempts, she finally manages to cure the Bear.

The Bear plays checkers. Masha interrupts him asking to feed her. The Bear cooks some porridge for her. But Masha doesn’t like it. The Bear goes off in a huff. Masha decides to cook porridge her self. But soon the porridge swells out. All the forest inhabitants will remember this day for long...

The Bear's little cousin, Panda, comes over to pay a visit. Masha immediately wants to pal up and spend time playing games. A competitive spirit arouses in our heroes as they can't share any thing between each other. The Bear quickly figures out that if he leads their rivalry in peaceful direction, they could greatly help him around the house.

The Bear decides to suit a big laundry in his yard, but yet he has no idea that soon he would have to pull Masha from a puddle and a jar of jam. But it’s not all- now the Bear has to sew new dresses every time when Masha will get wet or dirty.

The Bear finds a beautiful black piano in the forest. He happily takes it home, fixes and tunes it and begins to play some music. Masha couldn’t help staying away from this lovely instrument. She decides to become a world famous pianist, she asks the Bear to teach her how to play the piano.

The Circus Tiger visits his old friend Bear. The whiskered and stripped cat is utterly bewildered by Masha's behavior and tries everything to get rid of her. Nevertheless his changes his mind when he gets lost in the forest and Masha saves in the middle of the night.

The miracles always happen on New Year’s Eve. Masha finds a magical hat that grants gifts to all the forest dwellers. Masha runs happily around the forest in a clown outfit and brings joy to all the critters. The magical hat has a special gift for the Bear who has not been very lucky on such a dreamlike day.

Bright summer day. Bear, while gathering berries, meets female bear in the forest and arranges a date with her. Returning home, he starts cleaning the house and baking a pie. Once the pie is done, the Bear decorates it with strawberries. Masha eats them before starting to hiccup. The Bear tries all manner of remedies from a medical encyclopedia to stop the hiccups. In the end, hiccups spread to everyone including all other forest in-habitants.

Occasionally Masha finds an egg, from which a penguin hatches. The Bear has to take double care now. He cooks special dishes and builds mini aqua park for little penguin and Masha. Finally the Bear figures out that the penguin will be happy only in suitable weather conditions and send the penguin Antarctica on a little plane.

Panda - the Bear’s distant relative pay sone more visit to the Bear. They start making Chinese dumplings, but then Masha appears, with her own methods of cooking. And a simple cooking turns into a culinary master class with butterflies!

It is raining cats and dogs outside and the Bear is going to read a book. He is sure that Masha will stay home in such nasty weather. But soon Masha shows up on his doorstep and also wants to read. The Bear makes up his mind to engage the girl with magician’s box. Masha starts to test all the magic tricks on the Bear and he realizes that it was not a great idea. In order to have some spare time on reading, the Bear decides to hide in magician’s box, but Masha makes an even more interesting trick out of it.

The Bear's idea to hang a new picture frame on the wall ends up with a huge explosion. The Bear has to start a great repair. Masha and the other animals help Bear with this difficult job.
