It's Portwenn Fun Day and the village is buzzing with excitement about this major fund raising event. P.C. Penhale is in his element rallying the runners and whipping up support. The event sparks culinary rivalry between Bert Large (Ian McNeice) who runs Large's restaurant with son Al (Joe Absolom) and Mark (Tim Goodman Hill), the landlord of the Crab and Lobster pub. Louisa's mum Eleanor (Louise Jameson) arrives in Portwenn unexpectedly and Louisa is far from happy about her arrival. She hasn't seen her mother for years, so why the sudden interest?
