Cathy and Colin have returned from a luxury cruise and seem strangely keen to persuade neighbours Eric and Beth to join them on their next trip. However, it soon transpires they have an ulterior motive - getting hold of a cheap deal. With Eric and Beth politely declining, the determined couple have another target in mind. Christine, fresh from a PPI refund windfall, wants to crow about her good fortune, and Beth is railroaded into holding a celebratory barbecue - the perfect moment for the holiday hunters to pounce.
