The lonely and tough Jim Wilson is an efficient detective that frequently uses excessive violence to resolve his cases and even his partners do not approve his behavior. While chasing two cop killers, he blows the bladder of another suspect during the interrogation to get the information to catch the assassins. He is warned by his chief Captain Brawley to cool off, and when he beats another suspect on the street, Brawley sends him "upstate to Siberia" in the cold Westham to calm down and help the locals in a murder case of a girl. When he arrives, he visits the family of the victim, whose father Walter Brent is decided to kill the murderer. They chase the man through the snow, and after a car accident, they reach the isolated house of Mary Malden, a blind woman that lives alone in the middle of nowhere with her brother Danny that has mental problem. Brent and Jim are lodged by Mary to spend the night, and Jim is affected by Mary in a process of humanization and redemption.—Claudio Carvalho, Rio de Janeiro, Brazil
