It's Christmas Eve in the late 1940s and people have hunkered down in their homes to celebrate the holiday together. All except Happy Highmore, seasoned host of STAR Radio, who finds himself spending his Christmas alone playing tunes over the airwaves in his empty studio. As the evening progresses and the clock ticks closer to midnight, the grouchy man is lulled to sleep by the records he plays. Only to be awoken moments later by Jack Alonzo, his vivacious co-host with full STAR Radio crew in tow! Jack informs Happy they have a big show planned with three musical guests ready to dazzle their audience. But there's something suspiciously familiar about the acts that come trooping through the studio. Are they really who they say they are? As confusion, commercials, and chuckles ensue, will anything that happens during the Christmas special be enough to break Happy's sour mood?
