Zoom - It's Always About Getting Closer(2001)

The young Romanian Wanda works as a call girl. She has no idea that the reserved neighbor Waller has her constantly in his sights. She also has no idea that Waller is blackmailing her clients with his videotapes and dropping some of the money in her letterbox. One day, Waller and Wanda meet by chance in the hallway. When Waller learns that Wanda has to go procuring for her husband because he is holding her son hostage, he feels called to be her guardian angel and promises her a new, better life. Against her will, he frees her from the milieu and takes her on one last "tour". Together they visit her clients a second time and blackmail them again. Only this time the price is higher, because Waller and Wanda need a lot of money for a better life...
