A handicapped boy stuck in a wheelchair dreams of having a friend. Just when a toy airplane flies into his hospital room and magically turns into a boy, who takes him on an outing he will never forget.

An ancient Greek god, lost in time, finds himself in the apartment of a Russian schoolboy.

It's post-apocalyptic future. The group of boys does not realize that one of them is not quite a person... he's the "Mowgli Project". It is also unknown whether Mowgli himself knows about this.
