Plot: Three loser-type ex-students who earn too little money and don´t get laid as much as they want, try to change that by producing a home made porn movie starring themselves. They loan money from a pimp and begin casting the girls. When filming starts they find out that sex in front of the camera is hard work. Also you should know how to work a video camera. Frustration, relationship problems and cabin fever culminate in a dope induced garden orgy. But is it a film?
