France. Summer 1981: In a small village in southern France, a wilful English girl is falling in love. Frances Langley has fallen under Benoit's romantic spell, and their summer of love finds Frances willing to do almost anything for the handsome art collector, even hiding a precious artefact for him, stolen by the Nazis decades before.

England. Summer 2022: Frances's son, Harry, finds himself packing up the clutter and chaos of his late mother's home. Little does he know that his mother had sent a letter to Tabitha, the lost love of his life, begging the pair to find a priceless jewellery box, hidden in her cottage.
