Hemingway & Gellhorn recounts one of the great romances of the last century - the passionate love affair and tumultuous marriage of literary master Ernest Hemingway (Owen) and the beautiful, trailblazing war correspondent Martha Gellhorn (Kidman) - as it follows the adventurous writers through the Spanish Civil War and beyond. As witnesses to history, they covered all the great conflicts of their time, but the war they couldn't survive was the war between themselves.
