In 1940, as the shadows are lengthening over Europe, painter Louis Duval decides to leave his studio in Brittany and, in his small motor boat, make the short but perilous journey to England. His aim is not to flee from the enemy, but to join the Resistance to fight for his beloved France. He arrives in Dartmouth and finds his way to the boarding house run by the delightful young widow Barbara Hillyard, who is trying to make a living for herself and her young evacuvee Esme.
