In a coastal town, three thieves make an ill-fated journey to rob the region's legendary terrible old man. Livig alone in a decrepit house, the old man is rumored to possess exotic riches and gold acquired during a disappearance at sea nearly one century ago.

Donning animal masks and wielding knives, the malicious men penetrate the old man's overgrown property. They are quick to learn that they've been reduced a level on the food chain, as the terrible old man reveals that he's part fish, part swish, and all appetite.
