The terrifying reign of the shadows has ended. But in their exit, they awakened something unseen, something sinister, something malevolent. The malevolent spirit, hell bent on revenge, seeks to possess and live in the human flesh. One name recurs through its consciousness—Susan. In addition, Susan is unaware that her doppelganger has penetrated the walls of her home. The other Susan lingers, unseen, contemplating the right moment to reveal herself.
Meanwhile, Tahoe has foreseen a face to face confrontation between the two Susans. Worried about Susan, the team faces other dilemmas. Tahoe has undergone a silent but obvious change since channeling the great chief’s spirit and battling the shadows. Dylan, haunted by dreams of the night on Eagle Rock Mountain, begins to remember. Yet all of it must wait.
Tahoe’s prediction comes to pass. As two identical beings meet, the malevolent force intercedes, and a showdown begins, leaving Susan’s life hanging in the balance, and the investigators embroiled in a battle between life and death.
