PREVIEW: Baptiste, BBC One

Julien Baptiste is not the man we left at the end of series one. After enduring a horrific personal tragedy, Julien has pushed Celia away and is looking for any distraction - whether that be the bottom of a bottle or a new case - to consume him.

When Ambassador Emma Chambers’ whole family disappears in the Hungarian mountains, Julien finds his new case. He immediately travels to the resort where the Chambers were staying and entrenches himself in Emma’s world. Despite no longer being a Detective in any official capacity, Emma realises that Julien’s experience and capacity for understanding human nature will be integral to getting her family back.

When the case turns into a murder and kidnapping, Julien must work closely with the Hungarian police, including Zsofia Arslan, who at first rejects his offers of help but soon comes to see his value. Julien navigates a police force he cannot trust and obsessional media desperate for more information on such a high profile, international case.

British Ambassador to Hungary, Emma tries to wield her influence, but the layers of corruption and secrets prove too complex to unpick. Julien, Zsofia and Emma must work together if Emma is to be reunited with her family.

Baptiste returns Sunday 18th July at 9pm on BBC One.
