Becky has to go on holiday with her Dad, his new girlfriend, and her daughter Tasmin. Tasmin is only interested in music, clothes and boys! Becky on the
other hand only cares about saving the planet, endangered species and changing the world! Needless to say they really don't get on. In a cramped caravan journey to the Norfolk
Broads, Becky and Tasmin are going to have to come to terms with the fact that one day they may be sisters.
