Overview
Session 9 is a 2001 American psychological horror film directed by Brad Anderson and written by Anderson and Stephen Gevedon. The film stars David Caruso, Peter Mullan, Brendan Sexton III, Josh Lucas, and Gevedon as an asbestos abatement crew who take a clean-up job at an abandoned mental asylum amid an intense work schedule, growing tensions, and mysterious events occurring around them. Its title refers to a series of audio-taped sessions with an asylum patient that run parallel to the crew's experiences.

Plot
Gordon Fleming, the owner of an asbestos abatement company in Massachusetts, makes a bid to remove asbestos from Danvers State Hospital. Desperate for money, he promises to complete the job in only one week, despite requiring two to three weeks. His crew includes Mike, a law school dropout who is knowledgeable about the asylum's history; Phil, who is dealing with his grief over a recent breakup; Hank, a gambling addict; and Gordon's nephew Jeff, who has a pathological fear of the dark.
While surveying the job site, Gordon hears a disembodied voice that greets him by name. The men begin their job, and Mike discovers a box containing nine audio-taped therapy sessions that were recorded with Mary Hobbes, a patient who suffered from dissociative identity disorder. Mike begins listening to the tapes in the ensuing days. In the sessions, Mary's psychologist attempts to unveil details surrounding a crime she committed at her home two decades prior. Mary exhibits numerous personalities who have unique voices and demeanors.
