When an old man is found dead on the road - seemingly run over by a Hungarian au pair - police investigator Anna Fekete is certain that there is more to the incident than meets the eye. As she begins to unravel an increasingly complex case, she's led on a deadly trail where illegal immigration, drugs and, ultimately, murder threaten not only her beliefs, but her life. Anna's partner Esko is entrenched in a separate but equally dangerous investigation into the activities of an immigrant gang, where deportation orders and raids cause increasing tension and result in desperate measures by gang members - and the police themselves.
