It's Christmas Day and the Brockman family have decided to escape the festivities and head for the sun, but fate seems determined to intervene. Grandad has been taken ill and is languishing in the hospital from hell. Karen has toothache so her special yuletide treat is a trip to an emergency dentist. Ben is intent on getting into the Guinness Book of Records, preferably with a record involving knives, and their ditsy friend Jane is going to be looking after the house, with her ex-convict boyfriend. What can possibly go wrong?
