Knox Goes Away

John Knox (Michael Keaton) has killed people for money for years, and now a doctor tells him he has weeks before a fast-moving dementia takes his mind. Michael Keaton directs himself through a final stretch in which Knox tries to save his estranged son Miles (James Marsden) while Detective Emily Ikari (Suzy Nakamura) closes in. Every hour costs him another piece of what he needs to remember to get there.
