I am a movie director and I just received the following movie plot. Could you help me answer this question? If not, let me know by writing "Not answerable". Plot title: Never Cry Wolf Movie plot: A young, naive Canadian biologist named Tyler (Charles Martin Smith) (portraying the real-life biologist Farley Mowat) is assigned by the government to travel to the isolated Canadian arctic wilderness and study why the local caribou population is declining, believed due to indiscriminate wolf-pack attacks. Tyler receives a baptism of fire into bush life with a trip by bush plane piloted by an odd, adventurous bush pilot named Rosie (Brian Dennehy). After landing at the destination, Rosie leaves Tyler and his gear in the middle of a frozen lake in a sub-zero Arctic nowhere. Unsure of where to start, Tyler's indecision quickly imperils him when he runs into a traveling wolf pack until he is rescued by a travelling elderly Inuit native named Ootek (Zachary Ittimangnaq), who builds a shelter for him.Alone, Tyler's days are divided between research and mere personal survival, while nights are fraught with anxiety-born nightmares of wolf attacks upon him. He soon encounters two wolves which he names George and Angeline, who have pups, and discovers they seem as curious of him as he is of them, slowly dispelling their mutual fears. He and the wolves both begin social exchanges, even urine-marking their territories, producing trust and respect between them.As the spring season arrives and the winter snow slowly melts, Tyler (being a person of procedure) soon discovers the simple, blunt arctic is indifferent to his sense of order. First dealing with sub-freezing weather extremes, ranging from cold snow to warmer heavy spring rains, compromise his shelter, his paperwork duties, his research. Complicating matters further are an invasive horde of Arctic mice when they show up after the spring thaw: they are everywhere, frustrating him and the wolves. Yet the wolves seem to cope with the madness by eating the mice, which Tyler emulates in his own bizarre way to see if an animal can survive on mice alone.During the mild summer season, another Inuit named Mike (Samson Jorah) encounters Tyler, who was sent by Ootek for... My question: Where do Tyler and Ootek trek across?
