context: The film opens in 1934 with Winston Churchill (Albert Finney) being driven through the lush forests and countryside of southeastern England by his son Randolph (Tom Hiddleston). Churchill steps out of the car, strides to the top of a tall hill and gazes out across a broad valley. He vividly imagines his famous ancestor, the Duke of Marlborough, heroically leading a British army in battle on the verdant plains below.Returning to Chartwell, his Kentish estate, Churchill is in denial about the family's precarious finances. The upkeep on the estate and the maintenance of a sizable household staff are draining his bank account. The Wall Street crash of 1929 did serious damage to Churchill's investments. Accompanied by his wife Clementine (Vanessa Redgrave), Churchill is driven into London to speak to a half-empty Commons chamber at Parliament. He warns the few members present against allowing the loss of India, describing Mohandas Gandhi as a "seditious Middle Temple lawyer" and a "half-naked fakir." Churchill is in the political wilderness, unpopular with his more liberal colleagues who view him as an embarassing relic of a declining British Empire. Once the First Lord of the Admiralty, Churchill now fears that his illustrious career, stretching back to the battle of Omdurman, is at an end. While Churchiill addresses Parliament, his wife secretly visits a London banker to discuss their finances and explore household economies.Churchill soon receives a visit from Desmond Morton (Jim Broadbent), an intelligence advisor to the British Foreign Office. Morton is greatly concerned about the massive military build-up in Germany, where 8,000 pilots are in training. Prime Minister Stanley Baldwin (Derek Jacobi) and the British people are in the grip of pacifism, being only twenty years removed from the Great War horrors of trench warfare. Morton begins to recruit Ralph (pronounced "Rafe") Wigram (Linus Roache), a fellow Foreign Office official, to quietly monitor the Nazi rearmament threat and secretly report to him and Churchill. Wigram and his wife Ava (Lena Headey) are raising a mentally-challenged son named Charley, to whom they are completely devoted. Wigram is well aware how the Nazis treat the disabled.Churchill continues to beat the drum in Parliament about German rearmament, but he is ridiculed, needing hard facts and figures to substantiate his claims. The British government is downplaying Nazi strength in order to keep the peace and in hopes of reaching an accommodation with Hitler. Wigram is worried about German intentions and approaches Morton for advice. Morton tells Wigram that he requires detailed (and therefore classified) information to bolster Churchill's efforts. Wigram nervously begins passing top secret Foreign Office documents to Morton, who passes them along to Churchill. Armed with the new information, Churchill addresses Parliament again and begins to gain traction.Wigram and his wife are subsequently invited to Chartwell for a visit. Wigram confesses his fear of being caught while helping Churchill, but he receives reassurance that his involvement will be kept in confidence. Upon returning to work, Wigram receives a blunt warning from Foreign Office Under-Secretary Robert Vansittart (Tom Wilkinson) that Churchill uses people for his own ends.Adding to Churchill's woes, Clementine soon announces that she is joining a family friend on a four-month expedition to Komodo Island. Churchill is appalled and accuses her of selfishness. A huge fight ensues, for which Churchill is forced to apologize. Nevertheless, she embarks on the lengthy trip and Churchill finds himself at loose ends. He forces himself to "keep buggering on." His constant hectoring about Germany has galvanized his enemies in the government, who now seek to force him from office. Churchill's uncanny command of German rearmament details and his friendship with Wigram has aroused suspicion. Ava Wigram receives a surprise visit from Baldwin henchman Ivo Pettifer (Hugh Bonneville), who threatens to reassign her husband to a remote posting, where the special care required for Charley would likely be unavailable. He wants her to pressure Ralph into discontinuing his collaboration with Churchill. Incensed at the crude blackmail attempt, Ava rebuffs him.Clementine's prolonged absence and frequent written references to Terrence Phillip, a wealthy and dashing art dealer who is with her on the expedition, worry Winston. He fears that she has fallen in love with the man. Although her affections were tested, she eventually returns to an elated Churchill.Wigram becomes increasingly despondent over Germany's march to war. He worries that his assistance to Churchill may have been a mistake, that perhaps appeasement was in fact the right course. As he prepares for a scheduled defense meeting, his secretary reluctantly informs him that his presence isn't required. He wasn't invited. When Ava and Charley return home that evening, they encounter a melancholy Ralph. The following morning, Ava awakens to a beautiful overnight snowfall and a beloved husband who has died during the night. At his funeral, a devastated Ava tells Churchill, "Ralph's life was very precious to me. Please tell me that it wasn't wasted." Churchill reassures her that she should be very proud of him. Ralph understood the dangers facing him and acted bravely in spite of them.The inexorable slide into the abyss continues. Churchill soon hears Prime Minister Neville Chamberlain's ominous announcement that a state of war now exists between Great Britain and Nazi Germany. Churchill is summoned to London to join the War Cabinet as First Lord of the Admiralty. He and Clemmie bid farewell to Chartwell to begin their new life in London. Before he exits the car to report at the Admiralty Office, he emotionally thanks Clemmie for being rash enough to marry him, for staying with him through the years, and for loving him in a way that he never thought he would be loved. Winston Churchill steps out and walks alone into the Admiralty, embarking on the fateful course that eight months later would elevate him to Prime Minister during the war years. He is informed that a signal has already gone out to the British fleet: "Winston is back."
