The end of summer is fast approaching, but the Lumberjanes have bigger problems than just finishing their camp to-do list -- an evil force is spreading over their forest, sapping the life out of the flora and fauna, leaving only a grey forest behind. Known only as the Grey, this power has already taken the Lumberjanes' friends, freezing the Yetis and leaving the bear woman stuck in animal form! If the girls can't defeat The Grey, the Lumberjanes way of life will disappear -- and not just for the summer!
