The first of four special episodes combining new and unforgettable past cases. Stewart and Vic attempt to reclaim £5,400 owed by a man that Vic has met before, but are forced to seize a vehicle when the debtor refuses to pay. They also look back on a case previously featured in Series 4, Episode 2, where they tried to reclaim £2,700 owed by the owner of a garage, but the situation became volatile, forcing Vic to call the police. Brian and Del visit a man who owes £150,000 – the biggest debt in the show's history – to a friend who lent him money for a business venture. Del also looks back on a case featured in Series 3, Episode 1, where he and Kevin were assaulted by a violent debtor.
