Fun-loving primary school teacher Sophie Hunter-Brown is first up in Cardiff. Sophie is planning a Thai full-moon beach party as her theme for the night. This is despite the fact that she has never been to Thailand. Sophie's guests however are not convinced. Stewart is dreading a tacky student affair, Emma thinks the host must be a man, Huw is flummoxed about what a full-moon beach party is, and Gina thinks that she should wear an overcoat. Sophie has plenty of fun things in store for her guests including buckets of cocktails and a limbo competition. But as the evening unfolds there may be a shock in store for our party girl.
