Eddie Izzard stars in this funny, moving and inspiring factual drama about the pioneering work on radar by a little known team of scientists in the run up to the Second World War.

It is the mid-1930s and the storm clouds of WWII are forming in Germany. This film charts the work of Robert Watson Watt, the pioneer of Radar, and his hand-picked team of eccentric yet brilliant meteorologists as they struggle to turn the concept of Radar into a workable reality. Hamstrung by a tiny budget, seemingly insurmountable technical problems and even a spy in the camp, Watson Watt also has to deal with marital problems as he chases his dream. By 1939, Watson Watt and his team have developed the world's first Radar system along the south east coast of England - a system that, in 1940, will prove pivotal in winning the Battle of Britain.—John

It is the mid-1930s and Germany is making radical advances in weaponry, especially aircraft. Suspecting that a war with Germany is likely, the British War Ministry look to new and advanced inventions of their own. After aiming for something more radical - a death ray - they end up with the invention that saved Britain during its darkest hour - radar. This is the story of the invention of radar, and, in particular, the story of Robert Watson Watt, its inventor. We see his trials and tribulations of its invention, and the characters that were trying to undermine his project.—grantss
