Paddington station, eight a.m., rush hour. As the crowds ebb and flow, time suddenly stands still for two people: Fern and Elliott, ex-lovers who parted twenty-five years before and never expected to see each other again. Both will be travelling back through the station in exactly twelve hours that same day. They swap numbers and agree to meet. As the day progresses, both wrestle with their shared past and their separate present. And as the Paddington clock chimes eight that evening, their future will be decided.
