Ricky Gervais is back for a second run of his surprisingly touching and hard-hitting sitcom about Derek, played by Gervais, a helper at a nursing home. A year after the events of the first season, all the old Broadhill faces are back, alongside some new ones. Derek's happy that his dad's moving in, while Tom and Hannah are taking things to another level. Geoff, a volunteer, has joined the clan, but Dougie and Vicky have no time for him.
