In 1918, 18-year-old Ernest Hemingway volunteers to fight in the great war. Soon he discovers that what he imaginined to be an adventure is far more grim. During a shelling attack in Italy, his leg is severely wounded. Hemingway has taken a great deal of shrapnel, and the doctors at the field hospital decide that amputation would be the quickest and most effective way to deal with the injury. However, the idea of losing a leg horrifies Hemingway, and he pleads with Agnes, the Austrian nurse looking after him, not to let the doctors cut off his limb. Moved by Hemingway's concern, Agnes convinces the doctors to pursue other treatments, and she looks after him during his long and difficult convalescence. Love and passion bloom between the young and naive soldier and the 26-year-old nurse, but while he's eager for her to return home with him as he follows his muse as a writer, she regards him not as the love of her life but as a passing fling and thinks that he's too young to marry.
