As plans for D-Day loom large and Department Z work overtime to halt the leak of British secrets to Berlin, three cousins undertake their own covert operation: meeting in a cottage in Guildford to discuss a dark family matter in secret. As these two seemingly unrelated events collide, the cousins are drawn along a secretive trail that leads to a powerful spy ring. The team faces a race against the clock... infiltrate this tight-knit organisation, or risk devastating consequences.
