Windy Lake is a fictional First Nation in the midst of the boreal forest and a connection of lakes and rivers. The community is conflicted over a nearby mine, which has the support of the Chief and Council, but is a source of concern for First Nation families connected to the land. As part of the agreement with the community, the mine must do an archeological assessment of any new land they disturb. Unfortunately, soon after his arrival, the old archeologist goes missing. It's a perfect case for The Mighty Muskrats, a group of cousins: Sam, Chickadee, Otter and Atim, who use the mysteries they come across to explore their community, their culture, the land and its history.
