Rogue River (1951)

The story of Ownie Rodgers, the nephew of crooked Oregon police chief Joe Dandridge. A $70,000 windfall, bequeathed to Dandridge by a man he'd once framed on a bank robbery charge, unleashes innumerable family skeletons. Ownie is obliged to solve the long-ago bank job himself, and in so doing he discovers that his "faithful" girl friend Judy was in on the scheme.
