The King's man 2021

In 1902, British aristocrat Orlando, Duke of Oxford, his wife Emily, and their young son Conrad visit a concentration camp in South Africa during the Second Boer War while working for the Red Cross. Emily is mortally wounded during a Boer sniper attack on the camp. Before she dies, Emily makes Orlando promise never to let their son see the war again.

Twelve years later, Orlando has recruited two of his servants, Shola and Polly, into his spy network dedicated to protecting the United Kingdom and the British Empire from the approaching Great War. Conrad, eager to fight, is forbidden to join up by the protective Orlando, who persuades Lord Kitchener, Secretary of State for War, not to let him join the army.
