Harry Boyd, a hard-bitten refugee from failure in Toronto television, has returned to a small radio station in the Canadian North. There, in Yellowknife, in the summer of 1975, he falls in love with a voice on air, though the real woman, Dido Paris, is both a surprise and even more than he imagined. Dido and Harry are part of the cast of eccentric, utterly loveable characters, all transplants from elsewhere, who form an unlikely group at the station. Their loves and longings, their rivalries and entanglements, the stories of their pasts and what brought each of them to the North, form the centre. One summer, on a canoe trip four of them make into the Arctic wilderness (following in the steps of the legendary Englishman John Hornby, who, along with his small party, starved to death in the barrens in 1927), they find the balance of love shifting, much as the balance of power in the North is being changed by the proposed Mackenzie Valley gas pipeline, which threatens to displace Native people from their land.
