Over the years, Eric has convinced himself that he is truly Baron von Leppe. Realizing her error too late, Katrina goes with André and Stefan to stop Eric from flooding the castle crypt. Katrina's pact with the devil, however, makes her unable to walk on consecrated ground and she ends up burning to death after being struck by lightning.
