1914. Evie Munro is a Scottish fisher girl, working the herring season from Wick to Great Yarmouth. For Evie, every day is the same -- gutting fish at the docks, shoulder-to-shoulder with her friends, followed by fresh bread, a warm whiskey toddy and an early night. But when Germany declares war, everything changes. As her village begins to empty of young men, Evie's life is marked by a heartbreaking tragedy. Her happiness destroyed, she vows to join the war effort as an army nurse, caring for wounded soldiers on the imposing hospital ship Britannic. But as the war rages on and the ship comes under direct fire, Evie's courage is put to the ultimate test. Can Evie and the nurses of the HMHS Britannic save the day and heal their patients? Or will her life become one more casualty in Britains fight for freedom?
