"Chains" is the final episode of the BBC sitcom Blackadder II, the second series of Blackadder, which was set in Elizabethan England from 1558 to 1603. Power-mad and self-professed "master of disguise", Prince Ludwig the Indestructible kidnaps Lord Blackadder and Lord Melchett. They escape his clutches but Prince Ludwig infiltrates the palace during a fancy dress ball.

Blackadder and Melchett are kidnapped by the Spaniards and held for ransom. Blackadder does not speak Spanish, so he and the Spanish torturer engage in a lengthy game of charades to determine the exact insults, threats, and mode of torture (for instance, the Spanish torturer is forced to go through several roles in order to call Blackadder a "bastard son of a bitch", and Blackadder is unable to explain via body language the meaning of "fornicating baboon"). Prince Ludwig the Indestructible, a German pretender to the throne who mispronounces English words, interrupts just as the torturer is about to get started on Edmund; when Edmund does not recognize him, Ludwig reveals that he was once disguised as Big Sally, a waitress at The Old Pizzle in Dover. Edmund is horrified: he had an affair with Big Sally, unaware that it was Ludwig.

At Ludwig's request, Lord Melchett is dragged in screaming. Melchett does not recognize Ludwig, until Ludwig tells him that he once impersonated Flossie, a sheep at a monastery in Cornwall. Melchett is also aghast, having unknowingly had a sexual encounter with the madman.
