In
San Francisco, a man is discovered breaking into his own jewelry store. The FBI questions him and learns the man's wife is being held hostage at their home by a brutal extortionist who demands the store's diamonds for her life. During a
standoff at the jeweler's home, the extortionist shoots the family's maid and demands that he be allowed to bring the jeweler's wife to the docks. FBI agent Warren Stantin tails them, but his attempt to apprehend the extortionist leads to the jeweler's wife being shot in the left eye and killed, while the extortionist rigs a boat as a
decoy and escapes. Stantin trails him to
Washington, where a man has been found shot in the left eye at a mine in a mountainous forest. Convinced that the extortionist killed the man and stole his identity, Stantin learns that a fishing party led by local fishing guide Sarah Rennell went into the forest from the mine, and he enlists her partner Jonathan Knox to help find them; Knox, who wanted to search for Sarah by himself, reluctantly agrees. Meanwhile, Sarah's fishing party halts when a fisherman nearly falls from a ledge, and another fisherman, Steve, attempts to help him. When a gun he is carrying slips into a crack, Steve asks the fisherman to return it but then lets the fisherman fall, throws the rest of the fishing party off the ledge, and takes Sarah hostage, demanding that she lead him to
Canada. After crossing a treacherous gorge, Stantin and Knox make camp and discover the dead fishermen in a stream. The pair reach Sarah's cabin, where Steve and Sarah rested for the night, and find a note to the FBI in Sarah's handwriting, confirming that she is still alive. The pursuit continues into a snowstorm in the mountains, where Knox pulls Stantin the rest of the way so he can recover from exhaustion. The pair gain respect for each other, which improves when Stantin saves Knox from a
grizzly bear. Sarah breaks free from Steve, who fires his gun at her, alerting Stantin and Knox to their location; however, Steve recaptures Sarah and escapes in a
logging truck. Stantin and Knox arrive in
Vancouver, where they learn that Steve and Sarah broke into a home to rest and call a diamond broker. Stantin and Knox break into the broker's home and interrogate him to learn where he plans to meet Steve. The pair stake out the meeting place and find Steve holding Sarah, but Steve spots Knox. After a brief shootout, Steve carjacks an SUV and leads Stantin, Knox, and the
Vancouver Police Department on a
car chase. Stantin and Knox spot the SUV on a departing ferry, but police search the SUV and do not find them; Stantin realizes that this is another decoy, and he and Knox search a second ferry. Stantin finds Steve and exchanges fire with him before Knox distracts him and frees Sarah. When Steve runs away and takes a passenger and her children hostage, Stantin draws his attention and is shot multiple times. Steve prepares to execute Stantin by shooting him in the left eye, but he has run out of bullets; both men then fall overboard, and Stantin shoots Steve, killing him. Knox dives into the water to rescue Stantin, and the pair are picked up by a
rescue boat. ==Cast==
