chunk: After giving a guest lecture on criminal psychology at a local university, Dr Helen Hudson (Weaver), a respected field expert on serial killers, is cornered in a lavatory by one of her previous subjects, Daryll Lee Cullum (Harry Connick, Jr.), who kills a police officer and brutally attacks her. Helen becomes severely agoraphobic as a result, sealing herself inside an expensive hi-tech apartment, conducting her entire life from behind a computer screen and assisted by a friend, Andy (John Rothman).
