watched the very second episode of the twilight zone today. what's it about?

Street scene: Summer. The present. Man on a sidewalk named Lou Bookman, age sixtyish. Occupation: pitchman. Lou Bookman, a fixture of the summer, a rather minor component to a hot July, a nondescript, commonplace little man whose life is a treadmill built out of sidewalks. And in just a moment, Lou Bookman will have to concern himself with survival – because as of three o'clock this hot July afternoon, he'll be stalked by Mr. Death.

don't want to spoil it completely, but it's clever, funny, and in the end, quite heartwarming. plots along a bit slow for current day tastes, but what can ya do. it's good!
