In 1950s New York, Doris Walker juggles her job as a senior executive at Macy’s department store with raising her daughter, Susan, by herself. Whilst Susan dreams of having a father and a brother, her determined mother is far more concerned with organizing the Macy’s Thanksgiving Day parade – one of the biggest events in the Big Apple’s annual calendar – and renewing Macy’s deadly rivalry with the city’s “other” department store, Gimbel’s, in the run up to Christmas. When her regular Santa Claus turns up incapacitated moments before the parade begins, Doris is rescued by the sudden appearance of a certain Kris Kringle, a genial old-timer who bears a striking resemblance to the North Pole’s most famous inhabitant. Kringle’s success as a stand-in Santa at the head of the parade leads Doris to offer him the same job in Macy’s Christmas grotto. But no sooner is he installed than he starts to behave – well, strangely. And then he claims that he is, in fact, the real Santa Claus . . . Now spreading a wave of love throughout New York – and creating harmony between feuding department stores – is one thing. But can Kris Kringle also convince a psychiatrist, a courtroom, and the entire state of New York, that Santa Claus is not a myth? And, in passing, make Susan’s dreams come true?
