On the morning of the
Macy's Thanksgiving Day Parade, the man playing
Santa Claus is drunk. An old man named Kris Kringle indignantly complains to event director Doris Walker. Doris persuades Kris to play Santa in the parade. A success, Kris is subsequently hired to play Santa at
Macy's New York City store on
34th Street. The toy department head, Mr. Shellhammer, instructs Kris to recommend overstocked items to shoppers. Instead, Kris directs a woman to another store for the hard-to-find fire engine her son wants. Impressed, the woman informs Shellhammer that she will become a loyal Macy's customer. Attorney Fred Gailey, Doris's neighbor, takes Doris's daughter, Susan, to see Santa. After hearing Kris speak
Dutch to an orphan girl from
the Netherlands, Susan is amazed. Doris, who has raised Susan not to believe in
fairy tales, asks Kris to tell Susan "the truth", but Kris insists that he really is Santa Claus. Worried, Doris decides to fire Kris, but
R. H. Macy, the store's owner, promises bonuses to Doris and Shellhammer because of the positive publicity Kris has generated. To alleviate Doris's misgivings, Shellhammer suggests Granville Sawyer, the store psychologist, administer an evaluation for Kris. After doing so, Sawyer insists Kris is dangerous and should be put in a
mental institution. It is Sawyer's opinion that Kris will eventually display "latent maniacal tendencies". Meanwhile, Susan shows Kris a magazine photo of her dream house and tells him she wants it for Christmas. Kris promises to do his best. In the company cafeteria, young employee Alfred tells Kris that Sawyer convinced him that he is unstable simply because he enjoys dressing as Santa. Kris confronts Sawyer, eventually striking him on the head with an umbrella. Sawyer, outraged, takes Kris to
Bellevue Hospital. Tricked into cooperating and believing Doris to be in on the deception, Kris deliberately fails his examination and is recommended for permanent commitment. However, Fred persuades Kris not to give up and represents him in court. At a hearing before Judge Henry Harper,
District Attorney Thomas Mara gets Kris to assert that he is Santa Claus and rests his case, asking Harper to rule that Santa does not exist. In private, Harper's political adviser, Charlie Halloran, warns him that doing so would be disastrous for his upcoming reelection bid. Harper buys time by hearing further evidence. Fred calls Macy as a witness and gets him to admit that he believes Santa exists. Macy then fires Sawyer. Next, Fred calls Mara's own young son, who testifies that his father told him that Santa is real. Mara concedes the point, but goes on to demand that Fred prove that Kris is "the one and only" Santa Claus on the basis of a
competent authority by the following day. Meanwhile, Susan writes Kris a letter to cheer him up, which Doris also signs. When a New York Post Office mail sorter sees Susan's letter, addressed to Kris at the New York courthouse, he suggests delivering all of the
dead letters addressed to Santa to Kris, freeing up storage space. As court resumes, Fred is informed of the mail delivery; he argues that the
Post Office, a branch of the federal government, has acknowledged that Kris is the one and only Santa Claus by delivering the letters. When the judge insists on seeing the letters, postal employees empty many bags of letters on Harper's desk. Harper dismisses the case. Kris invites Fred, Doris and Susan to a Christmas Day celebration at his current residence, the Brooks' Memorial Home for the Aged. Susan loses faith in Kris when he admits he was unable to get her the house she wanted. However, after Kris offers Fred and Doris a route home that avoids traffic, Susan sees her dream house with a "For Sale" sign out front; Susan becomes ecstatic and runs into the house. Fred learns that Doris had encouraged Susan to have faith and suggests they purchase the house. Fred and Doris then spot a cane inside that looks just like Kris's. Fred begins to wonder if Kris really is Santa Claus. ==Cast==
