As the exorcism reaches a critical juncture, Tomas engages the demon in a desperate battle to save Andy's soul. Meanwhile, Marcus and Rose attempt to get the foster children off the island, but the demon has other plans. As the storm of the century descends upon the island, salvation may come from an unlikely source.

As the exorcism begins, the fate of the foster home hangs in the balance. This is an adversary unlike anything Marcus and Tomas have ever faced, and in order to save this family, the two of them must journey into the mouth of madness itself.

As Tomas and Marcus continue to investigate the strange incidents at the foster home, the demon finally makes its presence known. The two priests must race against the clock to find evidence of possession before it is too late. Meanwhile, Andy and Rose take the children on an overnight camping trip, setting them on a collision course with the supernatural presence on the island. Back in Rome, Father Bennett's uneasy partnership with Mouse takes a turn as disturbing new information about the conspiracy comes to light.

The situation at the foster home continues to deteriorate, as Andy tries to help his foster daughter, Grace overcome her agoraphobia. Meanwhile, Marcus and Tomas travel to Seattle where they encounter a new possession case, discovering a young girl who has been targeted by a force of pure evil. Father Bennett tracks down a rogue church operative named Mouse who is waging a one-woman crusade against the demonic conspiracy.

Six months after leaving Chicago, Father Tomas continues his training to become an exorcist under the watchful eye of his partner Marcus Keane. Their travels lead them to a troubled young woman in rural Montana, where their investigation puts them in the crosshairs of her extended family. But as Tomas' skills continue to grow, Marcus begins to worry that his apprentice is taking unnecessary risks. The action then switches to a secluded private island off the coast of Seattle, where Andy Kim runs a group home for at-risk foster children, whose lives are disrupted when the state sends a social worker to determine whether the foster home should be closed. Little do they know the true danger is yet to come: a malevolent presence that has set its sights upon one of the children in Andy's care.
