Maya Larkin is a former victim of demonic possession who is now devoted to religious work. She joins a team led by Father Lareaux that is dedicated to identifying individuals possessed by dark forces. As the group performs an exorcism on a troubled man named Henry Birdson, Maya unintentionally uncovers a mysterious plan involving religious texts and symbols. Her curiosity leads her to a prophecy indicating that a specific human will become the Antichrist on an imminent date. Convinced she must prevent this event, Maya zeroes in on Peter Kelson, a skeptical crime journalist who has unwittingly become part of the prophecy. Although unclear at first, Peter’s birth date and connections to the dark world hint strongly that he may be the vessel destined to bring about this catastrophe.

Determined to help Peter avoid his potentially dire fate, Maya initiates efforts to convince him of the unfolding threat. Peter, rooted in logic and his work as an author, dismisses her warnings and considers her beliefs absurd. Despite his reluctance, Peter gets drawn into a series of strange occurrences that chip away at his skepticism. Meanwhile, malevolent forces working behind the scenes become evident, intensifying tensions around Maya's quest for answers. As she delves deeper into Peter's life to find leads that could avert disaster, time becomes their enemy in a world where not everyone is as they seem. What started as a mission becomes a gripping exploration for both Maya and Peter—in which faith, destiny, and salvation collide.
