Giovanni Percolla lives in Catania surrounded by the attentive cares of his three sisters. He permanently acts like a Don Giovanni to hide his real poor "knowledge" of women. With his friend he moves also to Rome but women still continues to remain part of his fantasies. But Giovanni succeeded to build anyway a fame of "tombeur de femmes". One day he meets the real love of Maria Antonietta and decides to marry. Will things change?
