he story focuses on Tony Hughes, who in the summer of 2006, during the FIFA World Cup, travels from the United Kingdom to northern France for a holiday with his wife Emily and 5-year-old son Oliver. Not long after entering France, their car breaks down, forcing them to spend the night in the small town of Chalons du Bois. One evening, Tony and Oliver visit a crowded outdoor bar, where the quarterfinals football match is being watched. Tony loses sight of his son, never to find him again.
Eight years later, Oliver has not been found; the police have closed their investigation, and the couple are divorced. Although Tony never stopped looking for his son, after seeing a recent picture of the French village where a little boy is wearing a scarf identical to the one Oliver was wearing the day he disappeared, and that was specially made for him with a unique insignia, Tony gets back on track, and with the help of retired detective Julien Baptiste, who led the original investigation, he starts to put the pieces together while the police decide to officially reopen the case.
