Giulio, a teenage boy lives with his father. He is in love with his mother, Agnese because her hands were the first to welcome him. He reminds the last weekend they spent together. She takes care but doesn't love, she's lost in her thoughts and doesn't let anyone get closer, not even him. Two days to understand each other, two days to love each other, and to leave in the end. At her funeral, he steals the hearse and drives away.

意大利导演费德里克．费里尼的中期经典作《八部半》是其成熟高峰期作品，此后开始走向糜烂而至腐败，偏于肉欲放纵和自我沉溺，像《爱情神话》（六九年）和本片，都是糜烂颓废的出色力作。本片反映了十八世纪基督道德不振后的上流腐化放纵，费里尼尽情借题发挥，展现出精英文艺在人欲 横流下的腐烂情态。大情人卡萨诺华是在情场屡战屡胜的“性斗士"，不断猎艳，还参加造爱竞赛。但这大情人苦于人人只重他的性爱能力，不重视他经世济民治国的才学。而且女人们对他都“有性无爱"，当他衰老得失去性魅力之后，就只能把一个机械女人当作梦中情人，很可悲可怜。
