In a magical kingdom, a ten-year-old orphan girl named Alenka runs a small vegetable shop. In this land, there are unusual creatures called Potatiks — living potatoes with unique personalities and abilities. Alenka has ten Potatik friends who help her.
One day, a Merchant and his Servant arrive. The Merchant wants to buy the Potatiks, but Alenka refuses, explaining that in their country, people live with potatoes, not eat them. That night, the Merchant steals eight of the Potatiks. Two Potatiks escape and inform Alenka.
Alenka, with the remaining Potatiks, sets off on a journey to rescue her friends. Along the way, they face various challenges and dangers. The stolen Potatiks leave signs to guide Alenka.
