The Muppets... Scotland Yard... jewel thieves... lead to high adventure in London.
Kermit and Fozzie are newspaper reporters sent to London to interview Lady Holiday, a wealthy fashion designer whose priceless diamond necklace is stolen. Kermit meets and falls in love with her secretary, Miss Piggy. The jewel thieves strike again, and this time frame Miss Piggy. It's up to Kermit and the rest of the Muppets to bring the real culprits to justice.
