Giri/Haji premieres

The series follows the story of a middle-aged Japanese detective Kenzo Mori who comes to London to investigate the murder of a yakuza boss’ nephew and search for his believed-to-be-dead brother – the main suspect of the crime.

As he tries to get to the bottom of things, Kenzo befriends London policewoman DC Sarah Weitzmann and a Japanese-British sex worker named Rodney Yamaguchi.

His investigation brings him into contact with several less friendly members of the London underworld.

Watch it on BBC Two.
