In 2019, The Canadian Government sent seven scientists to investigate an environmental disaster in the Northwest Territories: all seven advisors vanished. When activist Annie Erickson learns that her sister is one of The Missing, she embarks on a dangerous quest to find her. Annie's investigation leads her to a region called The Lake of The Woods and to an uninhabited island believed to be haunted. As Annie investigates each lead, she allies herself with a rogue scientist and a political whistleblower. Together, they uncover a classified bioweapons program: The 7th Fire. As events unfold amid a global pandemic, Annie realizes that her mission has just begun.
