John Constantine is a seasoned exorcist and master of the occult who has condemned his soul to Hell due to a failed exorcism that led to the death of a young girl. Haunted by guilt, Constantine reluctantly returns to his work after discovering a “rising darkness” threatening the world. He dedicates himself to protecting humanity while seeking redemption for his past sins.
Throughout the series, Constantine teams up with allies, including Zed Martin, a psychic with mysterious abilities; Chas Chandler, his loyal friend with an extraordinary gift for survival; and Manny, an angel tasked with guiding Constantine. Together, they face various supernatural threats, from demons and ghosts to ancient curses and mythical creatures.
As Constantine delves deeper into the rising darkness, he uncovers a larger conspiracy involving the balance between Heaven and Hell. His fight against malevolent forces becomes personal as he confronts old enemies and learns more about the role he is destined to play in the cosmic battle.
Although the series lasted only one season, it gained a cult following for its dark tone, compelling lead character, and faithful adaptation of the Hellblazer comics, leaving a lasting impression in the world of supernatural dramas.
