Bill Pollard is the very image of a mild-mannered suburbanite. He is a calm and stable husband and father, and teaches biology at Thatherton Community College. He is also hopelessly addicted to internet pornography. The object of Bill’s lustful obsession is webcam vixen Dani Darling. He spends his nights secretly entranced by her scintillating images, keeping his illicit fantasies hidden from his wife and family. One day, new student Marissa Weaver transfers into Bill’s Monday-Wednesday biology class.
