New Year's Eve, 1999, Blackadder Hall. While entertaining his dinner party guests - Archbishop Melchett, Archdeacon Darling, Major George Bufton-Tufton and Lady Elizabeth - cunning-as-a-fox Lord Edmund Blackadder suggests a wager. To prove that he can travel through time with his fully operational time machine, built to the exact specifications of the great Leonardo Da Vinci, Blackadder bets £10,000 that he can retrieve any item of historical interest they request. Of course, the marvellous device is nothing more than a pile of planks ingeniously put together by Baldrick, and imagine their surprise when the mismatched duo discovers that the time-travel machine truly works. But tampering with history is never without grave consequences. Will the world be the same after Blackadder's trip across centuries?
