Family Liaison Officer Lisa Armstrong becomes a little too emotionally involved with a case (to the point where she might compromise it) concerning a pair of missing Morecambe twins to whose distraught parents she is assigned.

After dealing with the consequences of the case involving the missing twins from last season, the demoted Lisa Armstrong (Morven Christie) is brought back into the fold to assist with the murder investigation in Morecambe.
