Margo has spent most of her life without a family, and with a telekinetic gift she can't quite explain. Since losing her mother, she's felt more alone than ever. When her fiancé Sam takes her to his remote Iowa hometown to meet his family and begin planning their wedding, Margo finally begins to feel like she's home. But the feeling doesn't last long, and Margo soon feels out of place. Sam's family is different from what she'd expected. Not only is their obsession with a deceased televangelist unsettling, but Margo has begun seeing a mysterious figure from her past—a figure that she thought was put to rest with her mother's passing.

As Sam's family begins to take over the wedding plans, Margo tries to regain some control by turning to the town's sole wedding planner, who soon becomes her only confidant, perhaps because she reminds Margo of her former love. But the more Margo tries to distance her past from her future with Sam, the deeper his family pulls her in, forcing upon her generationally archaic traditions that border on ritualistic. As Margo unearths the family's dark web of secrets, she begins to suspect that she may have been brought here for a reason, and it may cost her her life.

The Ever End takes elevated horror to a new level with a queer, twisted, feminist story that will keep listeners guessing until the end.
