Years later, the Korean War is a distant memory for the parents hosting their children for a Christmas party. But when an old photograph rekindles those memories, they’re soon wrapped up in telling their children how they fell in love. As a nurse and a downed pilot, they’d found themselves on the run from the enemy—but the only thing that could snare them was true love.
