国民革命军北伐前，军阀割据地区法纪荡然；不肖嫖吏欺凌百姓，市井无赖鱼肉乡里，小人之行径可恶，小人之嘴脸则可笑。片中刘三麻子即小人之代表也。刘三由线民而成公安队员而至小队长，胡作妄为、丑态百出，东施效颦每令人喷饭。今日之社会自由而崇法与昔迥异，不容刘三等宵小存在。故本片采取喜剧方式，以博观众一笑。
A rich woman, Raffaella, and some friends rent a yacht to sail the Mediterranean Sea during summer. The sailor, Gennarino, who is a communist, does not like this woman but has to bear with her bad mood. One day she wakes up late in the afternoon and asks to be taken to land where everyone had gone earlier. Gennarino sets up a boat but during the trip, the boat breaks down. They spend the night in the middle of the sea.
