Dodger and the gang return to the lair to find that they have had a break in. As they creep in expecting the worst, the gang are relieved to discover it's long-term gang member Nancy.

Nancy's been given the boot from her job at Buckingham Palace and now wants to use Fagin's gang for revenge. She's got an elaborate plan to get into the royal bedroom via the dangerous chimneys and steal Queen Victoria's most precious jewel - The Burmese Star.

But with PC Duff and PC Blathers on their case, will the gang succeed or will they be double-crossed by someone else?
