Season three finds former British spy Sylvia Fox, played by Silent Witness star Emilia Fox, mentally and physically recovered from her abduction at the end Season 2 and back to enjoying her life in Italy. But she’s still waiting for answers from her ex-husband, Adam Haines, about his past dealings with her kidnapper. Across the season, Sylvia Fox is investigating the murder of the owner of a local winery, and probing the mystery of a beautiful young man found dead in the bed of a power couple who claim never to have seen him before. Meanwhile, Sylvia’s relationship with Carabinieri captain Giovanni Riva deepens, but the finalization of Riva’s divorce and his desire to set down roots in Umbria threatens Sylvia’s sense of independence. In the final episode, Sylvia experiences an emotional crisis as someone close to her suffers a violent death, and Adam returns, injured and in danger, to ask for Sylvia’s help, and test her loyalties to the limit.
