Hlongwane and his partner find it abandoned but while waiting for police hear the cries of a woman being robbed across the street. Hlongwane races to help her and chases off the robbers.A few minutes later a passing driver warns the team he's driven past a gang of armed hijackers at a junction less than 100m away. The police arrive and chaos erupts as shots are fired.Carjack City shows the sad reality of SA's hijacking horror: It's alarming that, despite being close to the Union Buildings in Pretoria, the hijackers have no compunction about firing automatic weapons.According to the documentary, the lack of police protection in many areas is the primary reason for the influx of guards in SA - about 400 000.Hlongwane has a family and risks his life for R22 an hour. The film crew interviewed hijackers who claimed they stole vehicles for export to African countries.
