Vladimir Zelenin

Twelve-year-old Valera lives with his parents in a small village. In the boy's family, everything is subordinated to one thing: the accumulation of wealth. Valera's life is also filled with this. He does not play or run around like other children, but works all day long. Even fishing is not a pleasure for the boy, but a way to earn more money. But one day while fishing, Valera met a stranger who asked him to find him temporary accommodation. Valera brought Arkady Sergeyevich to his home — and from that moment on, he had a true friend and protector. Under the influence of this man, Valera realized that he couldn't live the way his family did.

A film about boys dreaming of becoming astronauts. Two friends built an entire spaceport, stole their friend’s puppy Sharik for experiments and renamed him Marsik, trained by eating only herring paste from a tube, and fought with a greedy speculator named Zakurdaev, who mined his garden to keep the boys from sneaking in.
