Donald "Sully" Sullivan (Newman) is a worn yet spry hustler living in the peaceful, snowy northern New York state village of North Bath. He freelances in the construction business, usually with his dim-witted friend Rub (Vince) by his side. He is often at odds with Carl Roebuck (Willis), a local contractor, suing him at every opportunity for unpaid wages and disability. Sully's one-legged lawyer Wirf (Saks) is inept, and his lawsuits are repeatedly dismissed. As a way to irritate him, Sully openly flirts with Carl's wife Toby (Griffith) at every opportunity (which she enjoys). He is a regular at the Iron Horse Saloon, where he often has drinks and plays cards with Wirf, Carl, Rub, Jocko the town pharmacist, and Ollie Quinn, the town's Chief of Police.
