Summoned to the headmaster's office, brother and sister Rhys and Steph are about to get some very bad news. But not before Steph does some straight talking to her boyfriend and Rhys has an intimate moment with the school fishes.
On the way to their mysterious nan's house, Rhys is lamenting the state of the country. But when he's confronted by two lads on the estate, Steph has to step in.
Rhys and Steph arrive at their nan's house - but no-one's home. Biscuits and a brief discussion on the behaviour of ants help to pass the time. But eventually Rosie arrives home... and not with the warm greeting they were expecting.
