Enos's master plan to recruit a demon army is unveiled as a brainwashed self-help cult. Knowing that it might be the only way to stop him, David, Maria, Grace, and Bledsoe attend the life-changing seminar under the pretense of being new recruits. But once they arrive on Sangalo Island, they discover that Enos's trap may be impossible to escape.

Maria enlists Bledsoe's help to destroy a demon and free David from jail. Grace adjusts to life after possession, and Abigail grows stronger.
