"Hemingway & Gellhorn" recounts one of the greatest romances of the last century - the passionate love affair and tumultuous marriage of literary master Ernest Hemingway and the beautiful, trailblazing war correspondent Martha Gellhorn - 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.
