When Liam takes Calum for a walk along Greenock Esplanade, his friend Pinball arrives in a stolen car and insists on taking them joyriding along the coast. They drive up through the Cloch caravan (trailer) park where Liam sees a caravan for sale in a spot overlooking the scenic Firth of Clyde. Liam, who loves his mother very much, fantasizes that he, his sister, and his mother can escape to the seaside and live in the caravan, away from Stan and Rab's wrath. To purchase it he and Pinball steal a delivery of drugs from Stan's house and sell them, doing the very things Liam once hated – claiming that they will never get anywhere by selling cheap cigarettes. They soon develop 'entrepreneur skills' and raise several thousand pounds, which they pay as a deposit towards the caravan in Liam's mother's name.
