Sal and Chester Hooton (Lamour and Hope), an old married couple, are visited by their equally old friend Duke Johnson (Crosby), and the three reminisce about their previous adventure in the Klondike, Yukon. The film flashes back to the turn of the century. A man is murdered and two thugs, McGurk (Nestor Paiva) and Sperry (Robert Barrat), steal a map to a gold mine. The map and mine belonged to a man named Van Hoyden and the dying man tells Sal (Van Hoyden's daughter) the mine is in Alaska and to find a man named Ace Larson. Sal manages to get on the last boat to Alaska before McGurk and Sperry.
