新年前夕，香港青年唐龙（李小龙 饰）受远在罗马经营餐厅的陈清华（苗可秀 饰）之叔父所托，远赴罗马助陈清华一臂之力。原来，陈清华从父亲手中接管餐厅不久，当地的商业集团看中了餐厅所在的地皮，而陈清华想守住家业不愿出售，商业集团遂使出下三滥手段，日日派流氓骚扰，令餐厅生意难以为继。唐龙甫一到罗马，因语言不通闹出不少笑话，陈清华则以为强援是律师，岂料是一莽撞的乡下青年，不免失望。餐厅众服务员为了抵御流氓，自发学习空手道，但仍然被对方欺侮，危急时刻唐龙出手，将一众流氓痛打。不甘失败的商业集团欲致唐龙于死地，陈清华担心其安危劝唐龙离开，面对将陈清华绑架的下流对手，唐龙忍无可忍，与商业集团聘请的众多高手展开连番搏杀……©豆瓣
