S2E1 Doorway to Hell

After his defeat in "Bottle of Dreams," Lewis Vendredi hatches a new scheme. He utilizes a mirror he stashed away before his demise, hidden in an old house unknown to the cousins, which will serve as a portal to hell, allowing him to break free. Vendredi takes over the body of one of two convicts who have made their way to hell. To stop him, Jack must venture through the portal and destroy it from the inside, a daunting task he ultimately accomplishes.
