Filmmaker Alan Berliner chronicles his lifelong battle with insomnia in this intimate documentary. The cameras roll as he tries to quiet his overly active mind so he can get a decent night's sleep, capturing the details of what it's like to suffer from a chronic sleep disorder. As he struggles to find balance, his friends and family -- who endure the worst of Berliner's bouts with insomnia -- question whether he really wants to find a cure.
