A perfect living arrangement unravels when schedules become misaligned in a romantic comedy adapted from Beth O'Leary's novel of the same title. Tiffany (Jessica Brown Findlay) works during the day for a viral news website and lives in a one-bed London apartment from 8pm to 8am. She has never met her flatmate, Leon (Anthony Welsh), who works nightshifts in a hospice and sleeps in the same apartment in the same bed between 8am and 8pm. The couple communicate through Post-It notes and are slowly drawn into each other's chaotic orbits.
