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 Muppets to bring the real culprits to justice.
Miss Piggy is called “that pig fellow” and referred to as “he” once. Could be interpreted as intentional and triggering given how feminine Miss Piggy is, but she is presumably a cis female pig and it is not malicious.
