Sylvia Fox (Emilia Fox, Delicious) is a top British spy, but she's disillusioned with MI6 after one betrayal too many. In need of a respite, she heads to Italy for her niece's wedding. But when the groom goes missing, leaving a dead body behind, Sylvia has a mystery to solve-covertly, of course. Enchanted by the town of Panicale and longing to reconnect with her sister (Tara Fitzgerald, Game of Thrones), Sylvia buys a crumbling old house on a hillside and decides to start anew in Umbria. But this secret agent was never cut out for a quiet life, and she's soon tackling a variety of cases, from a skeleton unearthed in an archaeological dig to a kidnapped truffle pig and a blackmail scheme with diplomatic tensions. All the while, she grows closer to a handsome local cop, Capitano Giovanni Riva (Giovanni Cirfiera, American Crime Story), even as her ex-husband and ex-colleague, Adam (Jamie Bamber, Battlestar Galactica), tries to lure her back.
