Mr. Bean digs up Bruiser Snr's medallion and rushes off to the local museum convinced he's found treasure. Mr. Bean thinks he's just dug up a valuable coin in the back-garden and goes rushing off to the Museum to have it valued, little knowing that it's actually Bruiser Snr's much-loved but valueless fake gold medallion. Bruiser Snr wants it back; and forces Bean to break back into the Museum to get it.
