A boy and Moshom, his grandpa, take a trip together to visit a place of great meaning to Moshom. A trapline is where people hunt and live off the land, and it was where Moshom grew up. As they embark on their northern journey, the child repeatedly asks his grandfather, ''Is this your trapline?'' Along the way, the boy finds himself imagining what life was like two generations ago - a life that appears to be both different from and similar to his life now.
