It is another seedy night in Johannesburg South Africa when a group of women hit the streets to wreak havoc and take their pound of flesh. They call themselves “”knockers” and that is exactly what they do – “knock customers” They never sell sex and they are proud of it. Some of them work alone, others work in Bonny and Clyde teams, luring scarily horny men into their rooms where they rob the of their valuables, clothes and sometimes even their cars. With hidden cameras we filmed the knockers knocking up their clients in a showcase of fine-tuned knocking techniques and maneuveres as the girls take their revenge for the years of abuse and hardship on the streets. The Knockers were knocking everyone up and out.
