Dr. Cathcart and his nephew Mr. Simpson go on a moose hunting trip deep into the wilderness of northern Canada with their guides Hank Davis and the French Canadian Joseph Défago, along with their Indian cook, Punk. They split up to cover more ground, Dr. Cathcart with Hank and Simpson with Défago, but the rumor of a creature that wanders the wild where they are headed begins to stir in their minds.When Défago takes off unexpectedly, Simpson attempts to follow him, but Défago is so swift that he is unable to keep up. The strange tracks he leaves, however, reveal that Défago was chasing something else, something with even stranger tracks. Stranger still is the lingering scent of something unexplainable that those who have smelled it can only describe as the "odor of lions."Simpson somehow is able to make it back to the original camp alone. Dr. Cathcart and Hank are surprised to see him, especially without his guide. But when Défago returns on his own, he is somehow changed. Dr. Cathcart might know something of his condition, but it is Punk's response in the end that is most telling.
