Sally Phillips is back as Clare Barker, the social worker who likes nothing better than interfering in other people's lives on both a professional and personal basis. And in today's Big Society there are plenty of challenges out there for an involved, caring social worker. Or even Clare. These six episodes see her embracing hot-desking; checking expenses; worrying about redundancy - and trying to absorb some shattering news about Ray. Plus, there's an awkward moment when she bumps into Thomas' beloved ex-nanny (who Clare sacked); a crisis at the Sparrowhawk Family Centre and the unwelcome prospect of a visit from Brian's mother. Sally Phillips stars as Clare, with Alex Lowe as Brian, Nina Conti as Megan/Nali, Richard Lumsden as Ray, Liza Tarbuck as Helen, Sarah Kendall as Libby and Andrew Wincott as Simon.
