Sometime in the 1970s, the historian Lou is sent by her Institute to research the life of a nineteenth-century colonel on the island he once owned in the middle of a wide river in northern Ontario. A magnificent house remains with a shack behind where a huge male bear is chained.

At first Lou is afraid of the bear, but gradually she feels sorry for it, allows it into the house, and eventually into her bed. The experience leads her to reevaluate her life, her friendships, and her loves. The summer passes and a wistful Lou returns to the city, and the indifferent bear, to his captivity.
