A man with amnesia wanders the city, nicknamed "Kompot" by kids for his love of the school cafeteria drink. A group of students decide to help him recover his memory and identity, but their quest proves challenging.

Kompot, does not remember his name, who he is or where he is from, he just woke up one day in the hospital with multiple injuries and no memory. Now he is forced to wander around the city, sleep wherever he can, and eat whatever they give him, but he has not lost his human appearance and dignity, as far as possible in the circumstances. The children nicknamed him Kompot for his special love for the drink from their school cafeteria, where he is fed by a compassionate cook. A group of high school friends decide to help Kompot, find out the truth and try to return his real life, but "going through this quest and finding the key" turns out to be far from easy.
