In the episode, Uncle Albert comes home claiming to have been mugged and, thinking he has become a burden, decides to leave Nelson Mandela House.
Rodney attempts to look for another full-time job, though Raquel and Del remind him that his prospects are bleak, due to him being unregistered for income tax and National Insurance for ten years.
That night, at the Nag's Head, Albert plays dominoes with his friend and rival, Knock-Knock, with the both of them battling for the affections of Dora.
Two hours later, back at Nelson Mandela House, Del tells Raquel that he bought the Capri Ghia to drive her everywhere safely.
The Trotter brothers spend all day driving around London looking for Albert, including searching the Seaman's Mission and HMS Belfast.
He laments the fact that the old neighbourhood has been torn down for the housing development, while Del thinks of it as a huge improvement and starts to wax lyrical about what he plans to do when he can afford to move there.
Rodney enters and tells everyone that the skinheads in the pub were actually undercover police officers who had been placed on the estate following the recent muggings, and a biker gang was arrested for assaulting them.
Del's heart sinks and he admits that he asked the bikers to do it as a favour, since he knows their leader, and believed that they were responsible for mugging Albert.
