When Japanese ex-pat Naoka meets Henri, a middle-aged woman who is both wildly unconventional and is hiding something that she refuses to share, she finds herself introduced to a collection of oddities who share the same hindrance. They are all insomniacs. This chance meeting soon provides Naoka with a much greater problem, when she and Henri become inadvertently caught up with the Fresno-DeBeers family, whose daughter has been kidnapped. Henri is determined to ‘help’ the police with their investigation, and the Fresno-DeBeers to find their daughter, and enlists the assistance of the unwilling Naoka as part of her efforts. As they get deeper and deeper into the case, living among oddballs and eccentric insomniacs who live their lives during the hours of darkness, they encounter the often weird and sometimes dangerous characters who inhabit the night.
But can they really make a difference to the case? Are they really able to provide anything of value and will they find the Fresno-DeBeers’ daughter before it is too late?
