Photojournalist Jeffery broke a leg in an accident, and now he has to spend a boring day in a wheelchair as he travels a lot. In the midsummer of New York, the neighbors around him open their windows day and night. Jeffery, who is free, always likes to observe the neighbors around him through the windows. A glamorous dancer is wearing a bra and shorts and doing housework with beautiful dance steps every day; a composer who lives alone often sits at the piano and writes, and is no exception when doing housework; a childless couple is very hot Lying on the balcony on the third floor to cool off, put the puppy down to play every day; the wife of Mr. Su, a salesman on the second floor, was bedridden for a long time, and two people's corners could be seen from time to time; the single woman on the first floor seemed to be unable to find a partner, Jie Jie Fury called it "Lonely Heart"; after a newlyweds moved into the apartment, they were busy and intimate, then put down the curtains, and then rarely showed up. Jeffery passed the boring time while watching.
Jeffery is actually not lonely. In addition to the nurse Stella who takes care of his sick life patiently every day, there is also a smart and beautiful girlfriend Lisa who loves him fanatically. Stella always complained that he didn't marry this almost perfect girl as soon as possible, and Lisa continued to launch gentle offensives, but Jeffrey, who considered herself loose and free, was a little worried about whether Lisa could get along with herself.
The salesman and his wife at the opposite window had another dispute. That night, Jeffery found that Mr. Sue walked out of the house with a big suitcase in the rain three times. The next day, Jeffery found that Mr. Su was wrapping the knife and saw blade. Mrs. Su also disappeared from her bed where she had been ill for a long time. The puppy kept digging in the flower bed downstairs, and everything disturbed Jeffrey. Lisa came, and noticed that Mr. Su was preparing a large box and took out the jewelry and ring from his wife's handbag. From this, the two people came to the conclusion that Mr. Su had killed and divided the body.
Jeffery asked an old friend who was a police officer to investigate the matter, but it turned out that Mrs. Su went to recuperate in another place, and the old friend mocked Jeffery and others' nervousness. The puppy was killed, and Jeffrey, Lisa, and Stella became nervous again. In order to find the true evidence, the two ladies decided to look for evidence themselves.
Lisa was stuck in the room while searching for evidence at Mr. Su's house. Jeffery called the police in time to save her from being murdered. She signaled to Jeffery that she had found evidence and the salesman knew that she was being monitored. Mr. Su quickly found Jeffery, and Jeffery, who had limited mobility, could only use flashing lights to protect himself in the dark, delaying time. When the two were fighting, the old friend arrived with Lisa and the police, but Jeffery still fell downstairs.
It's daytime again, Miss Lonely Fangxin is admiring his work in the composer's house, Mr. Su's residence is being repainted, another puppy appears, and the female dancer falls in love with a short soldier. Newlyweds still often hang curtains. Jeffery was sleeping soundly in a wheelchair with his back to the window, his legs in casts. Lisa sat quietly on the next bed, put down the novel contentedly, and picked up an advertising magazine.
