At the recently opened Sadler’s Wells Theatre in 1930s London, identical twin ballerinas Olivia and Clara rehearse for the ballet Coppélia, a tale of obsession and illusion. But as their lives entwine with the story, fiction begins to blur with reality, and danger lurks in the shadows.
Olivia, the picture-perfect ballerina, unknowingly casts a spell on Samuel, a shy apprentice shoemaker who sneaks into the theatre to watch her dance. Meanwhile, rebellious Clara has been drawn into a passionate yet unsettling relationship with Nathan, a pianist whose grip on reality is slipping.
As rehearsals intensify, the sisters are pulled into a dark, sinister web where ambition, obsession, and fantasy collide. Will they escape the spell of Coppélia, or will the dance consume them?
