In the center of town, a group of boys is building a pigeon house in abandoned cortyard. But, instead of pigeons, uninvited tenants move in - a man and two children. The boys are trying to throw out the "intruders" but, during their efforts they become friends, and when workers come from township to demolish the illegal object, that is, the pigeon house, they are fighting the township's decision instead.

U centru grada, dečaci u napuštenom dvorištu grade golubarnik. Ali, umesto golubova, u golubarnik se useljavaju nezvani stanari - jedan čovek i dvoje dece. Dečaci se trude da izbace "uljeze", ali se tokom tog svog truda sa njima sprijatelje i kada iz opštine dođu da ruše bespravnu gradnju, to jest, golubarnik, dečaci se sada bore protiv odluke opštine.
