Sandy is in her fifties, and at a crossroads in her life: she's a teacher and respected by her pupils, but she feels she is being sidelined in favour of younger colleagues. So when her mother dies, leaving her a sealed envelope addressed to an unknown woman living in Naples, Sandy decides to head to Italy to resolve the mystery by delivering the letter herself.
She books herself on to a small sightseeing trip from Rome to Naples and the Amalfi Coast, hoping to meet some like-minded people along the way. Who is the mysterious woman she is searching for? And will Sandy find friendship, or even love, along the way...?
