In Sicily, the mine worker Carmelo "MimÃ" Mardocheo votes in the Communist Party candidate instead of in the Mafia's one believing that the suffrage is secret. After the elections, he loses...
Mimi is a Sicilian dockworker who loses his job when he votes against the Mafia candidate in what he thinks is a secret ballot. He leaves his wife behind and goes to Turin, where he meets and moves in with Fiore, a street vendor and Communist organizer. They have a child, he works non-union jobs, and again he comes to the Mafia's attention. This time they're impressed, promoting him to a supervisor's job back in Sicily. He must keep Fiore and the child a secret, which is fine with Fiore, as long as he never makes love to his wife. He doesn't, and when she becomes pregnant, he knows he's a cuckold. His personal revenge and the Mafia's tentacles then intertwine in tragicomic ways.
