A naive provincial, Kitsos, who lives in Athens, accepts to work as a doorman in the apartment building where his old friend Aris lives, in order to help him marry the owner's daughter, Poly. Because the latter is quite a difficult character, Kitsos is forced to play the fool. Then, he discovers that Poly is in love with another resident of the apartment building, the famous singer Yannis Vogiatzis. Poly's father assigns Kitsos to monitor his daughter, because he suspects something, while his maid manages to charm him, and marry him, and the apartment building is disturbed by his incredible antics.
