Love has always been the most powerful motivator humans know. It can push people beyond fear, reason, and even self-preservation. When love is present, it gives purpose; when it vanishes, it leaves behind obsession, doubt, and unanswered questions. One such story, rooted in love, loss, and unraveling truth, is now taking shape in the upcoming mystery thriller Vanished.

A gripping premise is only half the equation. What truly elevates a mystery is the people entrusted with carrying its secrets. A strong cast can turn silence into tension and glances into clues, and Vanished has assembled an ensemble.

Leading the series, Vanished are Kaley Cuoco and Sam Claflin, anchoring the emotional core of the story. Cuoco’s casting signals a character-driven mystery rather than a conventional thriller. Opposite her is Sam Claflin as Tom Parker, whose sudden disappearance sparks the entire narrative.

Surrounding them is a lineup packed with international talent and fan favorites. Matthias Schweighöfer appears as Alex Durand, while Karin Viard plays Helene Lando. Simon Abkarian steps in as Inspector Drax, grounding the investigation with gravitas.

The series is directed by Barnaby Thompson, while Preston Thompson is the writer. The four-part limited series is set to premiere on MGM+ in the US on Sunday, February 1, 2026. US viewers can access MGM+ as an add-on through Prime Video Channels for $7.99 per month.

And then comes the question every mystery lives or dies by: what really happened?

The series begins with what should have been a dream trip. Alice and Tom arrive in Paris, wrapped in romance. But during a train journey heading south through France, Tom disappears, without witnesses, without explanation, and without a trace. What initially appears to be a tragic accident soon feels far more deliberate. 

As Kaley Cuoco’s Alice navigates unfamiliar cities and mounting danger, she uncovers fragments of Tom’s life that do not align with the man she thought she knew.  Each discovery reframes their relationship, forcing her, and the audience to question whether love blinded her to the truth. 

Vanished positions itself as a slow-burning mystery driven by emotion rather than spectacle, one that asks whether knowing someone deeply is ever truly possible.
