Armando is the daddy, Cristiano is the adult son. Each of them lives his life in a different way respect the other: Armando is an old play-boy and often he "buys" his women with his money; Cristiano is a shy guy who lives in a community with other guys like him. The movie proceeds showing us, ironically, the differences, the different ways to think, to act, to treat the women between father and son.
