After losing his wife, Sam moved to Seattle with his son Jonah, who is eight
years old. One Christmas evening, Jonah calls a radio show and tells his
Christmas wish would be for his father to get a new wife. Sam receives
hundreds of letters from women all over the country, but the one from Annie
catche's Jonah's attention; in the letter she suggests to meet on Valentine's
Day on the top of the Empire State Building, since her fiance suggested to
spend that day in New York. Annie lives in Baltimore and has a fiance, but has
doubts about her coming wedding. She manages to find out Sam's address and
under the pretense of a business trip, traveles to Seattle. She doesn't dare
contacting Sam, but he notices her on two occasions. Annie flies back to
Baltimore. When his father starts dating a woman who laughs like a hyena (and
whom he doesn't find suitable for his father) and doesn't seem willing to
visit the Empire State's Building on Valentine's Day, he flies alone to New
York (thanks to his girlfriend who uses her mother's, a travel agent's,
computer to get him a plane ticket). Jonah spends the day on top of the
building when his father, who has discovered his disappearance on the morning
and has immediately flown from Seattle to New York, finds him. When they are
about to live, they finally meet Annie, who just had just broken up with her
fiance in order to honor the appointment she had given Sam.
