Ronnie Marcum, an up-and-coming self-help guru, was busted for paying illegal immigrants $3 an hour to package and ship his Be Your Own Success Shape books and CDs. Halfway through serving a 10-month sentence in a minimum security prison, he made his escape.
Marcum is working in the prison mailroom. As he prepares his deliveries, he leans over to an enormous prisoner named Arturo and whispers in his ear. Arturo explodes, and begins beating Marcum. The guards hold him back as Marcum escapes to make his rounds.
Marcum uses his position in the mailroom to sneak an envelope in to the warden in with the rest of the mail. The unlabeled, unsigned letter reads “NOW YOUR DEAD” and contains a heaping helping of something that looks a lot like anthrax, but is actually baking soda. The warden locks down the prison so a hazmat team can come in and clean up. Marcum sneaks into a supply closet to slip into the painter’s protective suit he ordered – a suit that is almost identical to the ones worn by the hazmat team – and then uses his assumed authority to walk right out of the prison.
Once out of prison, Marcum meets up with Ken Reily, a practitioner of his self-help philosophy and one of his most loyal followers. He asks him for a lift around town so he can pick up pages to his new book that he left in the care of people he trusted on the outside. Ken agrees, not realizes that there are no pages; Marcum has a score to settle.
Their first stop is the home of Mo Blakely, a former employee and associate of Marcum’s. Marcum breaks into his house and begins searching for something. When Mo arrives and finds him ransacking his apartment, he swears to Marcum that he doesn’t know where the item is. Marcum stabs him a few times to make sure he’s telling the truth. Once Marcum is satisfied that Mo really doesn’t know anything, he stabs him viciously in the neck, killing him. He returns to the car and tells Ken they have another stop to make.
At the home of another of Marcum’s former partners, Ken stumbles upon Marcum in a back room with his old partner’s dead body. Whatever Marcum is looking for isn’t there. Marcum then blackmails Ken into continuing to drive him around.
Ken pulls up to a young girl as she leaves school. As he tries to convince her to get in the car with him, Marcum comes up behind her, covers her head with a pillowcase, and throws her in the vehicle. She is the niece of Curtis Ridgeway, the last of Marcum’s former associates. Marcum calls Curtis and tells him that he’ll make a trade, his niece for the item he’s looking for. Curtis reluctantly agrees.
Once he gets the item – a tape containing evidence of a past murder – Marcum doesn’t stick around. He kills Curtis, sets fire to the tape, and leaves. On the way, he finds that Curtis’ niece had been released by Ken, so he puts a bullet in Ken’s skull as well. Then, using his history of hiding out from abusive inmates (like Arturo) he breaks back into prison and pretends that he never left. He was simply hiding from another beating.
Unbeknownst to the cons, Damien has been busy. Ray has received a half-dozen postcards from the escaped killer, who seems to delight in taunting him. As the cons enjoy an evening away from the prison as a reward for a job well done, Ray stays up late, pouring over the postcards and every other scrap of information he has on the madman. He hasn't forgotten what happened to Charlie, and the hunt for Damien is still well and truly on.
