Angels, caricatures of jazz performers Louis Armstrong, Cab Calloway, Fats Waller, and Jimmie Lunceford, tell Saint Peter that to get people to paradise he will need "rhythm" (the short's credits list no voice actors, but a member of the all-black jazz group the Four Blackbirds —possibly Leroy Hurt—provides the cartoon's celebrity impressions). The musicians go to Harlem and break into a performance of "Swing for Sale", and the Harlemites flock to listen. The film's climax takes on the characteristics of "a revivalist camp meeting" as the band makes its way to Pair-O-Dice, and people follow them in droves. The newcomers receive their halos, and in the cartoon's final gag, the Devil himself asks to be admitted.
