When the Home Secretary delivers a speech inside the largest area, known as Paradis City, she is kidnapped by masked men. Security Service agent Fredrika turns to Emir, a former MMA fighter facing a life sentence in prison, with an ultimatum - go undercover in Paradis City and find the Home Secretary if Emir wants to see his daughter again.
