As John Brighton is helping clean up his church one night, a distressed and frightened man shows up looking for help. John reluctantly decides to lend a hand and, as a result, comes face to face with genuine evil.

A young man named Donovan has been possessed by an evil presence, and even with the help of the church’s pastor, elders, and a demonology expert, all attempts to banish the presence are unsuccessful. As if that weren’t bad enough, John quickly learns that the evil he is facing seems to know intimate details about his son, particularly about the coma John’s son has been in for a year.

Through a dark maze of spiritual warfare and shaken faith, John discovers that the car accident and Donovan’s possession are linked by a dark secret that John must unravel to not only rid Donovan of the evil, but to potentially save his son’s life.
