Athanael (Jack Benny), the third
trumpet player in the orchestra of a late night radio show sponsored by Paradise Coffee (motto: "It's Heavenly"), falls asleep listening to the announcer, who is doing his best to prove it is "the coffee that makes you sleep". Athanael dreams he is an angel (junior grade) and a trumpeter in the orchestra of Heaven. Due to the praise of his girlfriend Elizabeth (
Alexis Smith), the assistant of the deputy chief of the department of small planet management (
Guy Kibbee), he is given the mission of destroying planet 339001 (Earth) and its troublesome inhabitants by blowing the "Last Trumpet" at exactly midnight, signaling the
end of the world. When he is deposited at the Hotel Universe via the building's elevator, he accidentally foils a robbery attempt by suave guest Archie Dexter (
Reginald Gardiner) and his girlfriend accomplice, Fran Blackstone (
Dolores Moran). Dexter blames Fran and breaks off their relationship. When Athanael prevents her attempt at suicide from the hotel's roof, he misses the deadline. Elizabeth persuades her boss to give him a second chance, and travels to Earth to inform him. Complications arise when two
fallen angels named Osidro (
Allyn Joslyn) and Doremus (
John Alexander), also guests at the hotel, recognize Athanael and learn of his assignment. They want to continue their pleasantly hedonistic life. While Athanael encounters trouble holding onto his trumpet by his inexperience with Earthly life, Osidro and Doremus hire Dexter to steal the instrument. Learning that Fran was rescued by Athanael, Dexter reconciles with her. Then, while she distracts the angel, Dexter's henchman Humphrey (
Mike Mazurki) steals the trumpet. Athanael, Elizabeth and her boss track the thieves to the roof. During a struggle, Athanael falls off the building, only to wake up from his dream. ==Cast==
