Lovejoy helps a noble lord to redeem a valuable possession he has pawned.

After revealing his talent for spotting a bargain on TV, Lovejoy discovers that perhaps he isn't as good as he thought. His attempts at conning a young couple backfire and he finds that making amends is much harder, and more expensive, than it appears.

While the true-to-form Lovejoy is selling a set of dodgy Gillray prints to a friend of Jane's, Eric discovers a stolen antique Bacchus hidden at their house. The police have their suspicions and the race is on to return it to the rightful owner.
