Having dealt with some extremely naughty sheep last year in the Outer Hebrides, this year the gang are in Poplar. Everyone is hoping for a nice uneventful Christmas, but of course that doesn’t happen! Sister Monica Joan is rushed to hospital, while Trixie is less than impressed to receive a subscription to a Marriage Bureau as a Christmas present. Meanwhile, the circus is in town as ex Time Lord Peter Davison plays Mr Percival the Ringmaster.
