Still a virgin after 15 years in a convent, the demure Isabelle earns her living in New York by writing pornography, which she researches by buying magazines and hiring videos. In a café she befriends Thomas, who has amnesia after falling from a window. In another café, an accountant called Edward is befriended by Sofia, who pushed Thomas out of the window because, she says, he introduced her to drugs at the age of 12 and made her into a celebrated porn actress. She now wants revenge on Jacques, a crooked businessman for whom both Thomas and Edward worked. Learning that Edward has data on disk that could destroy Jacques, she lifts the disks from him and directs him into the hands of Jacques' hit men, who torture him and leave him for dead.
