Young police officer MARI is exceptionally gifted in working undercover. VIHTA is a veteran cop who leads a very efficient drug squad.
When Vihta’s unit discovers a terrorist cell living under aliases in Helsinki, Mari uses an assumed identity to get close to the terrorist group’s leader, MADINA, known also as Shahidka, or Black Widow – a nickname she has earned by training young women to become suicide bombers.
As Mari forms an unlikely connection with Madina that forces the young police officer to re-evaluate her world view, she finds out Madina’s target is the president of Russia, who arrives in Finland for an energy conference.
Struggling to keep her true colors hidden from Madina, Mari becomes one of the Brides of Allah and trains to wear the vest of an martyr.
