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.

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 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.

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.

Masha wants to learn ice skating. But there's no-body around to teach her because the Bear had fallen asleep. However this does not confuse Ma-sha 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 enthu-siasm, 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 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 for-est inhabitants will remember this day for long…

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 eve-ry 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.

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 pays one more visit to the Bear. They start making Chinese dump-lings, 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 make up his mine 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.
