What is The Diplomat plot?

The full plot synopsis for The Diplomat was released in October 2022. 

The Diplomat follows Laura Simmonds (Sophie Rundle) and her colleague and friend at the British Consulate, Alba Ortiz (Serena Manteghi), as they fight to protect distressed British nationals in Barcelona, Spain. 

Mixing the roles of lawyer, counsellor and cop, Laura and Alba's diplomatic skills are stretched to the limit as they navigate the stream of surprising and complex cases that walk through the Consulate doors in need of their assistance.

The series opens with the death of Jay Sutherland, a young British barman working aboard a yacht in Barcelona’s exclusive marina. 

While the Spanish police believe that the death was a tragic accident, Laura supports the boy's grieving father, Colin (Danny Sapani) who is convinced something more sinister took place that night. 

As new, unexpected evidence emerges and a murder enquiry is opened, Laura comes up against resistance from unlikely places that puts her in real jeopardy in her search for the truth, uncovering possible links to organised crime and a conspiracy to bury the facts that reaches the heart of the British security services. 

Determined to deliver the justice Colin deserves, Laura discovers that exposing the secrets surrounding Jay’s death can come at a cost. Sometimes, knowing who to trust is perhaps the hardest challenge of all.
