The 1956 film "Miracle In The Rain" is a romantic film set during World War II in New York City. Arthur 'Art' Hugenon, a soldier stationed near the city, meets Ruth Wood, an office worker and they begin a romance shortened by his transfer to the Pacific war front and his death in combat. During the time that they are seeing each other, they visit an auction house and Ruth buys an ancient Roman coin and gives it to Art. After Arthur is killed in action Ruth becomes depressed and despondent. She begins spending time at a large Catholic church, specifically at the shrine of a saint. One day Arthur appears outside the church, hands her back the coin, and leaves. The prop coin shown in the film is a Roman coin of the Emperor Vespasian (AD 69-79). It could be either a real Roman coin or more likely a copy of one.

A narrator reads a prologue to the film:

Ruth Wood is a woman who works in an office in New York City. Her closest friend is co-worker Grace Ullman. One day outside, during a rainstorm, soldier Arthur 'Art' Hugenon introduces himself to Ruth.

Ruth lives with her mother Agnes Wood in a small apartment and has rarely dated men. Ruth's father Harry Wood, a musician, deserted the family when Ruth was a child, causing Agnes to be suspicious of men. Ruth tells Art about her mother but he convinces Ruth to take him to her apartment.

Agnes surprisingly tolerates Art, especially after Ruth shows him a piece of music written by her father which he plays on a piano. Art asks to borrow the sheet music so that his Army songwriter friend Dixie Dooley can write lyrics to the music. On another date Art and Ruth pass a small second-hand store which is holding an auction.

A small crowd has gathered at the auction.

Ruth holds up her hand.

Ruth is the only bidder and buys the coin for two dollars. She then examines the coin.

The coin is a Roman Sestertius, a large bronze or copper coin, and matches the coin in the reference book Roman Imperial Coins (RIC) as Vespasian number RIC-190. However this coin appears to be a copy of a real coin. The coin's inscription reads "IMP CAES VESPASIAN AVG P M TR PPP COS III" which means "Imperator Caesar Vespasian Augustus Pontifex Maximus TRibunitia Potestas Pater Patriae Consul 3." This inscription differs from what the auctioneer and (later) the priest reads as "Titus Flavius Vespasian, Imperator."

The coin reverse has the goddess Roma seated and the word "ROMA" and the letters "SC."

Grace asks "It looks quite antique, and it really does say Titus Flavius Vespatian. He was a Roman Emperor alright. I wonder if it's real? You never can tell about Roman coins. What ever made you buy it?" Ruth answers "Well I really don't know. All of the sudden I got the strangest impulse and I just had to have it." Ruth then gives the coin to Art who tells her that "I'm punch a hole in it and wear it around my neck as a lucky piece."

Back at the apartment, Art plays the father's song with Dixie's lyrics.

The song is "I'll Always Believe in You" and was written by Ray Heindorf, M.K. Jerome, and Ned Washington. In the city, Art sees Ruth and tells her that his unit is being sent to the war front.

Art shows Ruth that he is wearing the Roman coin.

Art's finger is over the top of the coin so it is not known if he has punched the hole in it which he told Ruth that he was going to do. They kiss goodbye and both promise to write to each other.

Ruth writes to Art every day but for several months receives no letters from him. Then one day a special delivery letter arrives.

The letter is from an Army chaplain (a cleric who works with soldiers):

Ruth tells the people who she works with what has happened and soon becomes depressed. She and Grace take long walks in the city.

The ornate building in the background is the infamous Dakota Apartments.

Although Ruth is not a Catholic, she and Grace have begun spending time at New York's St. Patrick's Cathedral, the city's primary Roman Catholic Church.

Ruth becomes especially interested in the shrine dedicated to Saint Andrew, one of Christ's Apostles, and has been lighting candles dedicated to the saint. Ruth then becomes ill with a cold and pneumonia and stays at her apartment. The Army songwriter Dixie Dooley has had Art's song recorded and played on radio stations. Ruth's father Harry hears the song and recognizes the music that he wrote. He decides to return to his wife which he has wanted to do for a long time. Ruth, very ill, summons enough strength to leave the apartment and head for the church. Just after she leave, Harry (her father) appears to be welcomed by Agnes. Agnes sees Ruth missing and calls Ruth's friend Grace who heads for the church. Outside the church, again in a rainstorm, Ruth sees Art and they have a tearful reunion.

Ruth asks why Art didn't write to her and he replies: "You can't send letters where there are no mailmen with little wings on their feet." They both declare their love for each other. Art gives her back the coin which now has a chain attached. She tells him "It's the lucky piece I gave you. A genuine Roman coin" and he tells her "You keep it now. I don't need it anymore."

He tells her "I learned something wonderful. Love never dies" and she replies "I'll always love you. Forever. Oh, Art." Art then disappears.

The a church priest finds her and sends an assistant to call for a medical ambulance. Grace arrives and the priest notices something clenched in Ruth's hand.

Here the coin surface looks smoother and more worn than the coin shown before. It is possible that a different prop coin was used which already had a hole and a chain.

The priest reads the inscription as "Titus Flavius Vespasian, Imperator." Grace then realizes how and from whom Ruth obtained the coin.

She tells the priest "She gave it to him. And he must have brought it back."
