England, 1936. Young surrealist artists, including René Magritte and Salvador Dalí, gather at the grand West Dean estate for a private exhibition. When a shocking murder occurs, Scotland Yard is called in and the estate is locked down.

A new incident shakes West Dean. As the surrealist artists begin to suspect one another, Scotland Yard's investigation starts to focus on a single guest. Paranoia spreads, secrets unravel, and new facts about Sheila's past come to light.

The guests hold a beautiful farewell, while Scotland Yard discovers who will receive a surprising inheritance. Magritte starts his own search for the truth, and new suspects begin to emerge on the estate.

New guests arrive at West Dean, bringing tension and poor manners. As Quant and Thistlethwaite race to connect dots, a masked figure with a face of roses emerges from the shadows. Suspicion grows. Is it a warning - or something dangerous?

Another disappearance? Tension peaks as the exhibition countdown begins. The estate reopens; the gala begins. Lord James' elite guests Picasso, Guggenheim, and Freud arrive, ready to turn surrealism into gold. Champagne, whispers, and a twist.
