February 1944. Six months since Nazi forces occupied Rome. Inside the war-torn city, the Contessa Giovanna Landini works for the band of Escape Line activists known as ‘the Choir’.

Her mission is to smuggle Allied soldiers to safety, all under the nose of Gestapo boss Paul Hauptmann. During a ferocious morning air raid a mysterious parachutist lands in Rome and disappears into the backstreets. Is he an ally or an imposter? His fate will come to put the whole Escape Line at risk.

Meanwhile, Hauptmann’s attention has landed on the Contessa. As his fascination grows, she is pulled into a dangerous game with him – one where the consequences could be lethal.
