Haunted by the aftermath of his father's suicide, Tom abandons his wife and seeks refuge at the lakeside cottage where his father met his tragic end. There, his tormented memories from childhood resurface, all intricately connected to an ancient, mystifying force lurking beneath the lake's depths, driving Tom inexorably towards madness. As Tom's communication dwindles into eerie silence, Kathy, desperate to rescue her husband, enlists the help of her brother Mark, a struggling entrepreneur, and Mark's compassionate yet inexperienced wife, Jess, a trauma and grief counselor. Unaware of the sinister malevolence seeping from the lake, Tom becomes a willing vessel for the same evil that claimed his parents and now threatens all who dare draw near.—The Deep Dark
