The Mighty Muskrats, four cousins from the Windy Lake First Nation, are back for another mystery!

The National Assembly of Cree Peoples has gathered together in the Windy Lake First Nation, home to the Mighty Muskrats - cousins Chickadee, Atim, Otter, and Sam. But when the memory bundle, the center of a four-day long ceremony, is taken, the four mystery-solving cousins set out to catch those responsible and help protect Windy Lake’s reputation! The history and knowledge passed down to each generation through the bundle is at stake! What’s worse, prime suspect and long-time bully Pearl takes off to the city with her older brother and known troublemaker, Eddie. If they’ve brought the burgled bundle with them, the Mighty Muskrats fear it may be lost for good. With clues pointing them in too many different directions, the cousins need to return the missing bundle before the assembly comes to an end.
