The Horn Blows at Midnight

Falling asleep during the Paradise Coffee ("The Coffee that Makes You Sleep") Program, the band's third trumpeter dreams he's Athanael, an angel deputized to blow the Last Trumpet at exactly midnight on Earth. But Osidro and Doremus, two fallen angels enjoying the physical pleasures of an earthly existence, try to steal Athanael's trumpet, enlisting the aid of suave jewel thief Archie Dexter. Athanael fumbles his first try when he saves Archie's accomplice, Fran, from suicide. His second chance seems doomed when he's forced to leave his trumpet as security for a meal he can't pay for. But he gets it back just in time for a final confrontation with his desperate adversaries, dangling with them from the roof, only seconds from Midnight. - IMDb
