Father Charles "Chuck" O'Malley (Bing Crosby), an incoming priest from East St. Louis, is transferred to St. Dominic's Church in New York City.
On his first day, his unconventional style gets him into a series of mishaps; his informal appearance and attitude make a poor impression with the elder pastor, Father Fitzgibbon (Barry Fitzgerald).
The difference between O'Malley and Fitzgibbon's styles is openly apparent as they deal with events like a parishioner being evicted and a young woman named Carol James (Jean Heather) having run away from home.
The most consequential difference arises in their handling of the church youth, many of whom consistently get into trouble with the law in a gang led by Tony Scaponi (Stanley Clements).
As she prepares to go onstage as the lead in a performance of Carmen, the two discuss their past, and she learns that her world travels with a previous opera company caused her to miss his letter explaining he had entered the priesthood.
O'Malley next pays a visit to Carol, now suspected of living in sin with Ted Haines Jr. (James Brown), the son of the church's mortgage holder.
She, O'Malley, and O'Dowd devise a plan to rent out the Metropolitan, have the choir perform it with a full orchestra, then sell the rights to the song, saving the church from its financial woes.
When Max Dolan (William Frawley), the music executive brought on to hear the song does not believe it will sell, the choir decides to make the most of its opportunity on the grand stage, and sings "Swinging on a Star".
[6] Filming locations included the following:[7] According to Bosley Crowther in The New York Times, Going My Way was "the best" of Crosby's career, which is "saying a lot for a performer who has been one of the steadiest joys of the screen.
"[8] Crowther, however, criticized the film's length while lauding Crosby, and wrote that "he has been stunningly supported by Barry Fitzgerald, who plays one of the warmest characters the screen has ever known.
"[8] Variety endorsed the film, saying: "Bing Crosby gets a tailor-made role in Going My Way, and with major assistance from Barry Fitzgerald and Risë Stevens, clicks solidly to provide top-notch entertainment for wide audience appeal.
The website's critics consensus reads, "Bing Crosby and Barry Fitzgerald are eminently likable, and film is pleasantly sentimental, but Going My Way suffers from a surplus of sweetness.
Going My Way was adapted as a radio play for the January 8, 1945, broadcast of The Screen Guild Theater starring Bing Crosby, Barry Fitzgerald and Paul Lukas.
