The show examines espionage through their friendship, the fallout of which affects East-West relations to this day.
Amongst the vibrant international community of the eponymous Spanish island, a British and a German detective with very different approaches to policing have a clash of personalities. Despite - or perhaps because of - their very different approaches, the sleuths form a perfect complementary partnership as they seek to solve a new crime on the island each week.
