There are five of them. Claire, who sits awake beside a snoring husband and a little boy who is not hers. Jacques, a psychiatrist at the end of his career whose lonely nights are punctuated only by anonymous phone calls. Michele, a retiree whose dark secret compels her out of bed and to church. Lena, a young goth who cannot brave the dawn, volunteering at a local cafe. Herve, a shy accountant who sits in bed, panicking about his job while scrolling through emails into the early hours. They have one thing in common: insomnia. As meetings led by sleep specialist Marie-Helene draw them together, friendships will be formed and confessions made... but will they discover what's keeping them awake? And more importantly: will they be able to get to sleep?
