Tomorrow is GCSE results day, and while passions run high, confidence is at rock bottom. They definitely need a plan. Back home, a new member of the Quinn household is causing chaos in the neighbourhood.
There's a huge buzz in the Quinn household as preparations are made for the annual day trip to Barry's amusement park in Portrush. Surely an unfeasible amount of sandwiches and a massive surfboard is all they could possibly need.
James's driving skills are put to the test as the gang set off with a van full of hooch and high hopes to an adult-free house in Donegal. Meanwhile, the Quinns visit local psychic Carlos Santini in the hope of making contact with a much-loved family spirit.
There is no bigger night in Derry than Halloween, and the gang have miraculously secured tickets to the gig of the century and the chance to meet their idol, Fatboy Slim. But when Da Gerry arrives unannounced, it becomes clear that life will never be the same again for the friends.
