Britain's secret weapon in the Battle of Britain is hidden in plain sight...

It is a vast radar network, designed to detect hostile aircraft and enable RAF pilots to intercept them before they reach their targets.

By summer 1940, the Nazis are aware of the new masts along the English coast but misread their significance.

Germany's secret service sends former Olympic competitor, Klara Falke, to Britain. Her mission: to gather local intelligence to enrich the Nazis' invasion plans.

Klara joins a group of Nazi sympathisers in northern England. Soon, MI5 is in pursuit, but she is not the only German agent plotting in Britain.

When the Nazis discover that the RAF is using radar as an early warning device, they vow to destroy the masts. For Klara, knowing who to trust is a matter of life and death.

Rooted in historical fact, Warbird is an intriguing adventure that twists and turns through the pivotal first twelve months of the Second World War.
