Stetko must have her badly frostbitten fingers amputated by Doc. She then finds the missing scientist hiding in her office. He tells her that he and his two companions found the plane and took the canisters, but the killer has them now. Before Stetko can protect him he is killed, but Stetko captures his killer, who is revealed to be Australian biologist Russell Haden. The base commander orders everyone to evacuate because of the murders. With Haden locked in the brig and the winter storm near, Stetko and Pryce search for the canisters. However, Haden manages to escape and starts pursuing Stetko and Pryce. The three end up outside the base in a cat-and-mouse chase while the winter storm happens, and just when Haden corners and is about to kill Pryce, Stetko arrives and cuts Haden's safety rope and he is blown away due to the storm, cracking his skull onto one of the base's support pillars, killing him instantly.
