Finding the truth can sometimes be harder than exorcising a demon... Jimmy Holiday, defrocked priest- turned- exorcist, is trying to make sense of his life. With his on-again-off-again witchy girlfriend moving in, Lucy- the spirit from his last exorcism hanging around, and a secret organization of exorcists hounding him, Jimmy is feeling the stress. When a stranger calls in the middle of the night asking for help with a possession, Jimmy is puzzled. Especially when the dude on the phone says he got his number from Jimmy's old mentor. Too bad his mentor has been dead for several years. After a mysterious silver flask arrives at his doorstep, Jimmy is left with two options: either ignore the phone call and the flask, or listen to Lucy and travel to Arizona to solve the mystery before all hell breaks loose- literally.
