Three Kingdoms

As the severed human head of an Estonian woman is found in a river in Hammersmith, two British detectives set off in search of her origins in Europe and how she came to be found dead. Fighting to cross international borders and language barriers, the pair enter a nightmarish world that will change one of them forever. Three Kingdoms tells the stories of trafficked women, the gangs and the police forces across Europe that attempt to control the trade.
