Gemma Arterton (Hansel & Gretel) and Saoirse Ronan (The Host) star in this supernatural vampire thriller as a brothel-operating mother-daughter duo on the run from the law, finding shelter in a run-down coastal town. When residents begin to die, the elusive pair's deadly secrets come to light. From the director of The Crying Game and Interview with the Vampire.
Selling her body to make ends meet, the ever-practical Clara (Arterton) soon meets shy and lonely Noel (Daniel May), who provides a roof over their heads in his seedy guesthouse, Byzantium. Clara, always looking towards the future, turns it into a ‘pop-up’ brothel.
Meanwhile Eleanor (Ronan), the eternal schoolgirl, meets Frank (Caleb Landry Jones), a kindred spirit who prompts her to reveal the truth - that she was born in 1804 but is still a teenager, that Clara is her mother yet is only a few years older, and that they must both drink human blood to stay alive. As the residents catch on to the deadly ruse, Eleanor and Clara face the haunting past that finally confronts them.
