Raj Bisram and Margie Cooper start a new road trip in the home counties. In spite of a slightly unreliable classic car they eventually end up in Bourne End in time for an auction. In a break from the emporia and antiques centres, Margie detours to the opera for a singing lesson, while Raj tries his hand at one of the world's oldest crafts - but will he be 'wheelie' good? Raj sees a profit in some opticians' paraphernalia on which he gambles half his budget. However, when both experts turn up to auction with a boat it becomes a battle for bidders. Who will sail to victory at the auction on the banks of the River Thames?
