Mary Berry, Mel Giedroyc and Sue Perkins join forces to surprise a community centre in the Rhondda Valley in Wales with a very special Christmas party and a whole host of surprises.
This year, Christmas is coming early for a Welsh community centre that was set up by mum-of-three Buffy after a run of closures, from the school to the post office, threatened to kill off community spirit. Buffy and her team keep the locals united by bringing together toddlers, teens and OAPs for bingo, food and fun, funded in part by public donations and sheer willpower. Mary, Mel and Sue help Buffy throw the locals an unforgettable surprise Christmas party, with Mary in charge of the Christmas feast and Mel and Sue on decorating duty. The threesome get to know the locals as they work against the clock to pull together the best bash the Rhondda Valley has ever seen, and reveal special surprises that ensure the centre survives and thrives for years to come.
