Synopsis

In a quiet little town, down a narrow backstreet, stand three tall wooden houses: one red, one yellow, and one grey. In these houses live a busy bunch children and hard-working grown-ups, cats and dogs, and no doubt a few smaller creatures as well.
On the roof of the red house nest the seagulls. In that same house, in the attic flat, lives Professor Manivald Mõtus, an emeritus professor of art history, whose wall hangings are said to be worth as much as the house itself. Hardly anyone knows about these tapestries—except the professor, his orphaned grandson Raivo, and their housekeeper Piret.
But one day, when the tapestries mysteriously disappear, the whole street is thrown into a flutter. Even the seagulls seem unable to keep calm. The courtyard children rally to help their friend Raivo and his grandfather.
“We’ll catch those thieves, don’t you worry, Grandpa,” Raivo assures him.
