Task: Question Generation
Input (English): This article needs an improved plot summary. (May 2015)A man is discovered breaking into his own jewellery shop in the dead of night. Questioned closely, it is discovered that his wife is being held hostage at their home by Steve, a brutal extortionist who demands the diamonds in the shop's safe in exchange for the woman's life. After Steve kills the family maid, FBI agent Warren Stantin (Sidney Poitier) hands over the diamonds, but Steve kills the jeweller's wife anyway, and escapes. Feeling that he has failed, Stantin becomes obsessed with finding Steve, and he chases Steve into the rugged forests of the state of Washington, where Steve joins up with a group of sportsmen who plan to trek into the wilderness on a fishing trip. Steve's plan is to kill them and force their guide, Sarah (Kirstie Alley), to lead him through the wilderness to the CanadaâUS border.Stantin must team up with Sarah's mountain-man boyfriend Jonathan Knox (Tom Berenger) to pursue Steve. Jonathan does not believe city slicker Stantin can keep up on a tough cross-country hike that includes some rock climbing, and Stantin is determined to prove himself. They pursue Steve and Sarah into the wilderness and eventually to the streets of Vancouver. The movie also featured a chase scene aboard the BC Ferries Queen of Vancouver. After a long chase, Stantin manages to shoot Steve in an underwater struggle.The killer's identity is not revealed until midway through the film. He attempts to evade detection by killing a member of a hiking expedition and taking his place. To keep the audience guessing as to the true identity of the villain, some of the hikers were played by actors known for playing bad guys: notably Clancy Brown (Highlander), Frederick Coffin (Mother's Day), Andrew Robinson (Dirty Harry) and Richard Masur (the vicious drug dealer in Who'll Stop the Rain).
