Der Strick um den Hals.

The country estate of Count Claudieuse is located near Paris. One night in 1871, it goes up in flames. Two shots are fired, the count is critically injured, and the countess and her children escape the flames with the help of the feeble-minded Cocoleu. Cocoleu accuses Jacques von Beaucoran from the neighboring estate of being the perpetrator. Jacques protests his innocence.
