Ford Windust is a resentful gold miner who has lost an arm, and he now confines his partner, Abel Lonegan, in chains while threatening him with a shotgun to ensure he continues to mine for gold. Windust contracts a fever, which indicates trouble for Kodiak.

Kodiak must retrieve a thief from the mountains and encounters difficulties with gold prospectors. Two fugitives pursue Kodiak, who is looking after a baby while also escorting the prisoner.
