When the body of an old man is found in an acid dump site, the team becomes enmeshed in retirement home drama. As they explore the case, talk of marriage and kids begins to dominate the conversation back at the lab.

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. Evil has a new home.

Tomas and Marcus attempt to escape the custody of Cindy's (guest star Zibby Allen) enraged family, while simultaneously trying to finish her exorcism. Rose conducts her inspection of Andy Kim's household and is concerned about Caleb's mental state. Meanwhile, Andy's neighbors offer to teach the children farming skills, but there's something sinister behind their intentions. Additionally, Verity (Brianna Hildebrand) may be hiding something from the rest of her foster family. Then, Father Bennett tries to warn the Office of Exorcism of a new threat, but finds his attempts railroaded by menacing forces.

The situation at the foster home continues to deteriorate, as Andy tries to help his foster daughter, Grace (Amélie Eve, “When Calls The Heart”) 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 (Zuleikha Robinson, “Still Star-Crossed,” “The Following”) who is waging a one-woman crusade against the demonic conspiracy.

As Andy confronts the strange incidents taking place on the island, his foster home receives a surprising new addition. Marcus investigates a series of natural disturbances with the help of a local wildlife biologist, while Tomas continues to question the strange visions that led him to Seattle. Meanwhile, Bennett's uneasy partnership with the enigmatic Mouse takes a dark turn.
