A fruit seller is threatened by a protection racket, who obtain false photographs of her lawyer son in an attempt to coerce her into letting them invest in her business on the docks. The racket has not reckoned on the tenacity of Dora and her son, however; or on her good friend Chief Ironside.

The Chief travels into the mountains to spend the weekend with an old friend, only to be snowed in following a bad blizzard. Trapped in a small cabin, Ironside discovers that his friend is now an addict, violent and unpredictable without the fix he cannot get.
