The Voyeur, a handsome Ca' Foscari University professor of photography, lives with his father. His father, who is also a retired professor (I can't imagine what good students these two can teach), is now paralyzed in bed, and his mother has long since died. So the father is taken care of by a sexy female nurse. When Doudou was a child, his mother often walked in front of him in pajamas as thin as cicada feathers, and once peeped at his parents' passionate belching, which led to a severe mother-love complex and voyeurism in slaves Doudou is married, and his wife's name is Sophia, a girl who looks very much like Doudou's mother (played by one person, can it not be like). But after marriage, Sophia decided not to live in Doudou's house, and Doudou was reluctant to abandon his father, who was sick and bedridden, and the two had to separate, and there was a rift in their relationship. One day, Doudou, who was looking for information, heard movement in his father's room, and found through the air window that the female nurse was flirting with her father, and Doudou peeped obsessively... A few days later, the nurse who had been trying to seduce Doudou told the slave a strange thing: before Sophia had left, she had seen a girl walk into her father's bedroom at night, and the girl looked like Sophia from the back... According to Ding Fatzi's routine, of course, Doudou went to the beach to solve ideological problems, and the beach was full of cool beautiful girls and decrepit brothers, who were making out one-on-one. After looking at it for a while, in Doudou's eyes, those girls had become Sophia, and he figured it out again: he was deeply belching Sophia. Doudou finds Sophia's place to live, confesses his longing for her and wants to reunite with her. Sophia revealed the secret: on the day of the wedding, she was forced by Doudou's father. What is puzzling is that after the two of them are having fun, they still go to the old house to live with Doudou's father
