In a large courtyard live three cousins ​​who share the same name: Christos Delimanis. The first is a constable, the second is a communist and permanently unemployed, and the third is a notorious petty fraudster. One day, the constable Delimanis arrests a beautiful young woman, Effi, for sneaking into the house of her sister's lover to steal some love letters. Effi comes up with a pile of lies about who she is, but in reality, she is the daughter of the Minister of Public Order. As a result, the fortunate constable Delimanis is transferred to the General Security Department, accepted into the Police Academy, and ultimately wins the girl's heart.
