Julia's life is comfortable, if unremarkable, until her sister's brutal murder opens old wounds. She finds solace in her sister's best friend, Sophie, but when Sophie reveals the extent of her sister's online life, Julia becomes convinced that the truth about her death lies deep in the dark, sordid world of online chatrooms and internet sex.
What begins as Julia's search for the truth about her sister quickly turns into an exploration of herself and her own desires. After all, the internet is her playground, and why be just one thing when you can be as many as you like? What could possibly go wrong? After all, it's only cybersex, isn't it? No one's going to get hurt.
But then she meets the dark and mysterious Lukas in an online chat room, and things begin to get very dangerous indeed.
