The true story of a young couple who meet, fall in love, and become engaged during the uncertain days of World War II, "Cal & Jo" is based on 85 letters written in the early and mid-1940s by Cal when he was in training, overseas, and back home again. From very different backgrounds, their relationship faces seemingly insurmountable obstacles, and Cal's letters lovingly express how deeply he misses Jo. He has no idea when he will see her again, and plans for marriage give him hope and purpose throughout the war. Yet his dream is unexpectedly shattered when he finally returns. This story is a remarkable display of resolute determination in the face of grim historic events and a parade of personal challenges. Providing stirring inspiration and uplifting encouragement, Cal and Jo are two ordinary people whose relationship does not have an easy start, yet who choose to be together through one of history's darkest hours.
