In an era of great change and great beauty emerged the character of James McNeill Whistler. Considered by some to be one of the great innovators of 19th century art, he was a contemporary of the impressionists, much admired by Van Gogh and Manet. Boldly experimental and famously witty, Whistler disrupted the strict conventions of Victorian society in pursuit of a new cult of beauty, creating “art for arts sake” and earning himself a place in the history of great art.

Tate Britain is now holding the first major retrospective of Whistler in three decades. This blockbuster exhibition promises to reawaken the world to just how important Whistler is to art history, uniting world-famous masterpieces with rarely seen works.

In the 72 hours leading up to D-Day, all the pieces are in place except for one key element – the British weather. Britain’s chief meteorological officer James Stagg (Andrew Scott) is called upon to deliver the most consequential forecast in history, locking him into a tense standoff with the entire Allied leadership. The wrong conditions could devastate the largest ever seaborne invasion, while any delay risks German intelligence catching on.

With only his trusted aide Captain Kay Summersby (Kerry Condon) to confide in, and haunted by a catastrophic D-Day rehearsal, the final decision rests with Supreme Allied Commander Dwight D. Eisenhower (Brendan Fraser). With only hours to go, the fate of the war and the lives of millions hang in the balance.
