The count seals off his wife and her lover. It's quite long to get there. And a bit crazy they don't realize the door is being sealed off, brick by brick.

Nice to see an early D W Griffiths film (I saw it on the Internet Archive). Although it's silent, there's clearly a plot hole - they can't "hear" the king raving with jealousy when there's just a curtain there, yet later on when there's a brick wall, he can hear them perfectly. Hmm...
