John Constantine was approached by Det. Angela Dodson, who needed his help to prove that her sister's death was not a suicide. The deceased woman was a devout Catholic and Angela refused to believe that she would take her own life. She turned to Constantine for assistance because he had a reputation for dealing with the supernatural. In reality, he was a demon hunter with a singular purpose on Earth - to send demons back to the Netherworld. John himself had been to hell and knew he was destined to return there upon his death - but hoped his good deeds could secure him a place in heaven. As he looked into Isabel's death, he realized that demons were trying to cross over into the human world, and his battles led him into a direct conflict with Satan. The supernatural forces at play tested Constantine's resolve and pushed him to his limits, as he fought to protect humanity from the darkness threatening to consume it. Through his encounters with both angels and demons, Constantine navigated a treacherous path, using his wit and cunning to outsmart the forces of evil and ultimately uncover the truth behind Isabel's tragic demise.
