The Missing: Season 1

In 2006 Emily and Tony Hughes and their little boy Oliver are on holiday at Chalons Du Bois in France. Tony and his son visit a bar which is crowded due to patrons watching a football match on television, to get a drink, but when Tony turns round Oliver has gone. Tony contacts the local police and asks for English-speaking Laurence Relaud to continue to be involved with the investigation. Parisian detective Julien Baptiste soon joins and leads the search and issues an abduction alert. Emily's parents Penny and Robert turn up, Robert suggesting that Oliver has been kidnapped out of revenge. Also on the scene are journalist Malik Suri and the English police liaison officer Mark Walsh with his young son. Eight years later Emily has moved on and is now living with Mark. Tony however has never stopped trying to find Oliver and, accompanied by Julien, who is now retired, visits a house in the village where there is evidence that Oliver has stayed. He rings Emily, who in turn contacts Malik, who has written a book about the disappearance.

Tony is annoyed when Mayor Deloix refuses to reopen the case, despite fresh evidence; Vincent Bourg, a known sex offender, is brought in for questioning; Suri bribes policeman Ziane for inside information; Bourg attends to a secret meeting with Ian Garrett.

The victim becomes the accused as Tony battles to prove his case. Meanwhile in present day France, something horrifying emerges.

Julien interviews Rini; A further clue is provided by the sighting of a van owned by Karl Sieg, a suspected trafficker, seen outside the house where Oliver was photographed; Tony visits Ian and learns that he's helping, as his daughter, Molly, vanished years earlier.

In 2014 Vincent Bourg visits Garrett's wife Mary, and Rini is able to help locate the suspect Karl Sieg, living in Belgium under an assumed name. This is an advance on eight years earlier when her efforts to sound out her brother about the Romanian gang had disastrous results. Emily goes to England to see Mary Garrett, and Tony takes matters into his own hands.

In 2006, both Tony and Emily are struggling. In the present day, Tony and Julien make a breakthrough.

It is 2009 and three years on from Oliver's disappearance there has still been no significant progress made in the case. Tony and Emily are having marriage problems but then a surprise turn of events brings both Tony and Emily back to Chalons du Bois. In the present day, the information that Tony, Julien and Emily received offers them a tenuous lead.

The truth about Oliver's disappearance finally comes to light, as the action moves between 2006 and 2014. But what does the future hold in store for Tony, Emily, Julien and Mark after all this time? Can any of their relationships ever be whole again?
