Thirteen-year-old Pierre Trudeau learns he’s spending the summer in the Yukon and Northwest Territories, instead of with his friends in Montreal. As if that’s not bad enough, he’s forced to work with a know-it-all Dawson City boy named Pierre Berton who thinks Trudeau is a big city snob. But the pair of Pierres call a truce after their fathers’ gold camp is attacked by something vicious -- and maybe supernatural.
