When a helicopter needs rescuing

It was supposed to be an ordinary day spent at the aviation museum. But when the children discover a damaged Mi-2 helicopter that introduces itself as Terezka, they persuade their teacher to repair it with the museum's owner. And so, a school project is born to save the helicopter so it can continue rescuing people and animals!
The children are already looking forward to flying it and seeing the world from above. But saving it won't be that simple. They need to find a group of adults to help with the repairs. Will they succeed?
