Rei would do anything for those she loves.
As her best friend, Abby, struggles to cope with the sudden loss of her husband, Rei and her closest girlfriends take her to a beautiful lakeside house nestled in the forests of the Pacific Northwest, hoping that a weekend of support from long-time friends will help Abby along her road of emotional recovery.
But as the young women get settled, Rei begins to notice there’s something wrong with the place. Could this peaceful, idyllic location be hiding an ancient evil below the waters of the lake? Or are the problems wholly within Abby herself, who seems to be losing her grip on reality? When unexplainable, nightmarish things occur, Rei realizes this weekend getaway may turn into their last outing.
