When someone goes missing, lives are irrevocably changed. Those left behind are plunged into a sense of limbo: not knowing why their loved one has left and worse still, if they are still alive. Missing is a procedural drama series set in a busy but under resourced Missing Persons Unit in Dover, run by DS Mary Jane Croft. Mary harbors a dark personal secret: a missing sister of her own. It is her journey to face up to her past that runs through each episode and provides the emotionally charged dénouement of the series. Starring Pauline Quirke (The Sculptress, Birds of a Feather) and Mark Wingett (The Bill, Eastenders).
