What is sleepless in Seattle about?

Sam has been living in silence with his 8-year-old son Jonah since his wife Maggie died of illness. He refused the comfort of his friends and the introduction of remarriage. He believes that true love only happens once, and he will never find a woman like Maggie again. In order to adjust his mood, he decided to leave Chicago and go to Seattle to live a new life. It's been a year and a half. Anne, a Baltimore journalist, is engaged to her boyfriend Walter. She decided to spend Christmas in Washington with her boyfriend. On the bus, Anne turned on the radio and listened to the emotional hotline, just as Jonah called to find a wife for her father. Sam was very angry, but under the patient persuasion of the host, he told his experience. He knew Jonah needed a new mother, but he knew he would never find a perfect home like his old mother. Anne was deeply moved by this sad story. When Anne returned to the office after Christmas, she found that almost all her colleagues were talking about it. Legend has it that 2000 women want to get in touch with Sam. Annie tells herself that she loves Walter, but strangely, she cares about Sleepless in Seattle. Persuaded by his colleagues, Sam decided to date a lady named Victoria. Annie is moved to tears every time she listens to the recording of that program. She finally wrote to ask Sam to meet at the top floor of the Empire State Building on Valentine's Day. Jonah thinks Victoria is not suitable for her father, but she is very close to Anne's letter. Anne came to Seattle in the name of reporting and met Sam and her friend Susie. She mistook Sam's girlfriend and gave up meeting Sam. They only met. When Anne came back, she decided to give up this strange feeling completely to love Walter and ignore dating. Since Sam didn't plan to go to new york for an appointment, Jonah sneaked on the plane and went to new york alone to meet "Annie". But he couldn't find Annie. After careful consideration, Anne also told Walter her emotional experience during this period and returned the ring to him. Walter has noticed her change, and he accepted the breakup calmly. Knowing that Jonah had gone to new york alone, Sam also arrived there. When it was dark, Sam finally found his son waiting for him on the top floor of the Empire State Building. Annie finally decided to go on a date, but when she arrived, she only saw a rucksack. Just then, Jonah and his father, who left the bag, came back here. As soon as the two sides met, they immediately understood that the other side was the person they wanted to meet and the partner they wanted in their hearts. Jonah reached out his hands and held his father and Annie. Three people walked into the beautiful night together.
