The film opens with Bing Crosby, a famous radio singer, delivering a farewell performance at a nightclub, where he sings My Silent Love and, at the crowd’s request, Auf Wiedersehen, My Dear. Later, he happens to board a train at the same time as a young woman, Marian Bradley, and they are mistakenly showered with confetti intended for another party. The passengers and a train porter assume they are newlyweds and present them with a perambulator and two baby dolls. Marian, not recognizing him, tries to impress by saying she is engaged to Bing Crosby. When she says that it is the first night she has not heard Bing sing, he tells her that he has a portable radio. As his berth in the sleeper train is the one immediately above hers, he says that he will play it for her. In the upper berth he simulates radio tuning noises and then sings Ev’ry Time My Heart Beats accompanying himself on guitar.
Subsequently, Marian’s friends see a newspaper report about her engagement to Bing Crosby. Gilbert Sinclair is indignant and says that it was taken for granted that he and Marian were engaged. Marian denies any such arrangement and is then told that Bing has telephoned to say he is arriving that afternoon.
When Bing arrives, he tells Marian that he is Jack Smith, a reporter, and that he had put news of her engagement in the press. She confesses that she lied and is in an embarrassing position with her friends and he promises to help her. Their conversation is overheard by Gilbert and when Bing meets Marian’s friends and explains how he met Marian, Gilbert tries to expose him and wagers his Cadillac car that Bing is an imposter.
To prove his identity to Marian’s friends and to a police patrolman who holds the car keys and Bing’s five dollar stake, Bing sings his signature tune Where the Blue of the Night (Meets the Gold of the Day), finishing the song as he and Marian drive off in the car leaving Gilbert floundering in the swimming pool after resisting the loss of his automobile.

In a bustling era when the glow of neon signs lit up nightclubs and the clatter of train wheels set the rhythm of everyday adventure, a famous radio crooner steps off the stage with his signature charm. Bing Crosby—playing himself—delivers a breezy farewell to a packed lounge, his smooth baritone drifting over the crowd like a warm tide. The atmosphere is thick with the easy‑going humor and slap‑stick energy that hallmark Mack Sennett’s two‑reeler comedies, promising a light‑hearted romp that teeters between romance and farce.
A chance encounter on a moving train launches the story into a delightful swirl of mistaken identity. When a celebration’s confetti rains down on an unsuspecting pair, the passengers and a bemused porter assume the duo are newlyweds, presenting them with baby dolls and a perambulator as if they were part of a staged tableau. The mix‑up sets the stage for a playful tug‑of‑war between reputation and reality, as the celebrated singer finds himself improvising a lullaby‑like serenade to win over a young passenger who is eager to impress yet oblivious to his true fame.
Enter Marian Bradley, a bright‑eyed traveler whose quick wit and penchant for dramatic flair match the film’s breezy tempo. She spins a tale of engagement to the very star she has just met, weaving a comedic knot that draws both characters deeper into a game of charming deception. Their banter crackles like the static of an old radio dial, hinting at a romance that could bloom amid the confusion, while the surrounding passengers provide a lively chorus of reactions. The tone remains effervescent throughout, balancing quick‑paced slap‑stick moments with the gentle twang of a crooner’s guitar, inviting the audience to wonder just how much a simple misunderstanding can spark when fame, humor, and a touch of romance collide.
