Synopsis: The Ministry of Ungentlemanly Warfare

It follows a true story about a secret British World War II organization: the Special Operations Executive. Founded by Winston Churchill, their irregular warfare against the Nazis helped to change the course of the war and gave birth to modern black operations.

In late 1941, during World War II the United Kingdom is struggling to halt Nazi Germany's attempts to take over Europe, with London regularly suffering bombing runs at the hands of the Luftwaffe. With their supply and aid ships constantly sunk by German submarines, Brigadier Colin Gubbins, with the indirect backing of Prime Minister Winston Churchill, prepares to initiate Operation Postmaster, an off-the-books black-ops sabotage mission intended to disrupt the Nazis' U-boat resupply operation on the Spanish-controlled island Fernando Po. While SOE agents Marjorie Stewart and Richard Heron depart by train, Gubbins enlists Gus March-Phillips to assemble a ground team to destroy the Italian supply ship Duchessa d'Aosta and two tugboats attached to it.
