Drama set in a busy missing persons unit.

The young au pair of a wealthy couple goes missing and MJ suspects that she may be pregnant. The team tracks down a therapist she's been seeing, hoping he can give them the answers they need.

Eighty- year-old Beth is convinced her friend Polly is missing, but Amy is suspicious when she can find no trace of her at all.

MJ receives news that her department is to be joined by a High Potential officer - DC Josh Kemplin - and fears that this is DCI Ford's way of keeping a firmer eye on the department. Show less
