Zucco is the proprietor of a creaky little inn (both he and the Inn are called THE BLACK RAVEN) and during the course of an hour's viewing time he plays host to an assorted group of unusual guests. It's a stormy night in town with thunder crashing and rain flooding the roads, and on top of that the bridge is out. Among the waterlogged patrons seeking shelter are: a formerly wronged business partner of Zucco's who'd like to kill him, a geeky embezzler looking to get away with $50,000 stolen loot, a gangster who's also interested in said loot, a young couple looking to get married behind the back of the girl's objecting old father, and dad himself - who's also hot on their trail.
