Rose uncovers an embarrassing truth while investigating an improper teacher-pupil relationship, and Nitin wins the job of cleaning Elm Heath council's most toxic kitchen

In the opening episode of the comedy about a group of long-suffering Children's Services social workers, former copper is tasked with grassing on the rest of the team as she has no personal allegiances - or friends.

Everyone is entirely unaware that one of them is about to be taken hostage by a violent man with two children in care, a personal grudge against Rose, and a full bladder.

Rose's mum has dementia. There's no way of looking after her unless Rose can pass her off as work experience and craftily get her assessed by the Elderly Care team upstairs.

Nitin is getting a haircut, because Nat's fixed him up with a date and Nitin badly 'wants some'. Meanwhile, PC Harris calls an Emergency Strategy Meeting at Children's Services.

It's judgement day at Elm Heath Childrens Services and Denise wants outstanding cases closed, or heads will roll. And then there's the regular prank call about the abandoned baby!
