Synopsis: In turn-of-the-century Czechoslovakia, two sisters are rivals for an inheritance. One is oblivious to the contest, the other is quite mad but very determined. When the insane one tries to test the poison she means to kill her sister with, she accidentally kills Morgiana, her pet cat. This motivates her to fake a suicide so that she can be put away in a madhouse. However, accidents conspire to make her faked suicide a real one.
