In a modern, high-tech megacity (à la Zootopia) inhabited by anthropomorphic animals, lives the Rabbits family: a father, a mother, and their children—a brother and sister named Bunny and Marusya. The kids never sit still; they want to experience everything firsthand but don't think about the consequences of their actions or staying safe. Luckily for them, real superheroes live in the city: super-squirrel Angel, super-hedgehog Chuk, and super-mega-wolf Stan. From their hero headquarters (a tall tower on the roof of a skyscraper), the heroes keep a close watch to maintain order in the city. They will come to the rescue and explain to the mischief-makers how to behave correctly in any situation.
