The Diplomat plot 

In The Diplomat, Laura Simmonds (Sophie Rundle) works at the Barcelona consul and alongside her colleague and friend Alba Ortiz (Serena Manteghi) works hard to help the multitude of British nationals who end up in trouble in the Spanish city. 

As the series opens we see her supporting the father of a young British barman who died unexpectedly while working on a yacht in the city’s notorious marina. The local cops are convinced his death was an unfortunate accident but the boy’s grieving father Colin (Danny Sapani) is convinced something sinister has taken place. Soon Laura and Alba’s quest for justice uncovers links to organized crime and the British security services, placing them all in danger from those who will go to any lengths to keep the truth hidden.
