The White Slave Trade.

Anna, a beautiful girl from a poor background, is offered a well-paid position as a lady's companion in London. Anna's boyfriend, the sceptical Georg, suspects that the job offer is too good to be true, but Anna dismisses him and reports to the London address. The stately home in England turns out to be a whorehouse that imports women from Denmark. Anna manages to overpower her first client but is unable to escape.
