Jack Thornton struggles to win enough at cards to fund his journey to the Alaska gold fields. His fortune turns when he buys Buck, a sled dog who is part wolf, for $250 to save him from being shot by an arrogant Englishman also heading to the Yukon. Traveling with Shorty Houlihan, who has just been released from jail for opening a letter containing a map to hidden gold, Jack rescues Claire Blake, the woman whose husband was the letter's intended recipient. Thanks to Buck's strength and intelligence, Jack wins a $1,000 bet, securing vital supplies. As he and Claire grow closer, Buck becomes the bond between them.
