Two Swedish girls have been found dead on the outskirts of Brussels. The circumstances surrounding their deaths point to a vicious trafficking operation and the Swedish branch of the Black Hearts motorcycle gang. When another girl disappears from the same area, A Unit sees a shocking pattern. Shortly thereafter, a suspected kidnapper is found brutally murdered and the connection to Black Hearts becomes even more puzzling. Is someone else behind it? The missing girl’s fate now rests entirely in A Unit’s hands.
