🗝️The Guest (2025): Secrets, Obsessions, and a Stranger Who Shatters Everything – Plot, Cast, Release Date & Where to Watch

💔 “Every guest brings a gift. Some bring the truth. Others bring destruction.”

This September, BBC One invites audiences into a world of toxic friendships, fractured marriages, and dangerous power games with The Guest — a chilling new four-part thriller from Quay Street Productions and BBC Cymru Wales. Starring Gabrielle Creevy (In My Skin) and Eve Myles (Keeping Faith), the series premieres on 1 September 2025.

🕰️ The Story Behind the Stranger

At its core, The Guest explores what happens when the past refuses to stay buried.

Ria Powell (Gabrielle Creevy) is trying to rebuild her life and marriage after betrayal, clinging to the fragile hope of forgiveness. But her world is upended when Fran Sharp (Eve Myles) — a woman from her past — appears at her doorstep, uninvited and unsettling.

As Fran becomes entangled in Ria’s life, their friendship spirals into something darker. Secrets resurface, loyalties fracture, and the line between friend and enemy blurs. “She came into my home like a shadow, and suddenly, I wasn’t safe anymore,” Ria confesses in one chilling moment.

🎭 Cast & Characters

The series boasts a stellar British cast:

• Gabrielle Creevy as Ria Powell, a woman desperate to hold her life together.

• Eve Myles as Fran Sharp, the enigmatic guest whose charm hides dangerous intent.

• Sion Daniel Young as Lee Mace, caught in the fallout of Ria and Fran’s bond.

• Julian Lewis Jones as Simon Sharp, Fran’s husband, hiding secrets of his own.

• Clive Russell as Derek Abbott, a patriarchal figure whose influence runs deep.

• Emun Elliott, Joseph Ollman, Bethan Mary-James, and Kimberley Nixon round out the ensemble, each character adding another layer of intrigue.

🌀 Themes: Power, Obsession & Betrayal

Written by Matthew Barry and directed by Ashley Way, The Guest is more than just a domestic thriller. It’s a study of how charisma can corrupt, desire can deceive, and the closest relationships can be the most dangerous of all.

With its toxic power dynamics and psychological warfare, the series recalls the sharp tension of The Servant and the unsettling intimacy of Killing Eve.

As one character ominously warns: “Once you let someone inside, you can never control what they’ll take from you.”
