Benny plays a big band trumpeter who falls asleep and dreams he is an archangel, sent to destroy earth because persecution and hatred have soared out of control. A light-hearted, farcical approach to the apocolypse that's quite enjoyable, despite Benny's longstanding jokes about being ashamed of it. The plot involves the third trumpet player in the orchestra of a radio program, named the Paradise Coffee Program, who falls asleep listening to the reading of the advertisement: "The coffee that makes you sleep." He dreams he is the angel Athaniel, a trumpeter in the orchestra of heaven, who is such a terrible musician he is relieved of his position and sent on a mission to earth. He is entrusted to blow the Last Trumpet at midnight, but complications in the plot ensue when two fallen angels, named Osidro and Doremus, want to continue their physical existence of pursuing pleasures. While Athaniel encounters experiences of mortal life, such as eating food and the need for money, the fallen angels try to prevent Athaniel from going through with his mission by having his trumpet stolen.
