For years, Vietnamese children and teenagers have been disappearing in Germany. Those responsible are unscrupulous human traffickers whose networks span continents. The young Vietnamese are smuggled into Germany via Russia and Eastern Europe. Many end up in the world of crime, working as slaves for the Vietnamese mafia. This film tells their story. One high-ranking investigator describes the phenomenon as "modern slavery". This is how many children and young people are brought from Vietnam to Germany: They are crammed into vans, loaded into refrigerated trucks, on the road for months, held along the way in abandoned warehouses or apartments. They are beaten, raped, exploited, they fear for their lives. They are lured by the prospect of a better life, as promised to their families by the criminals.
