Sonya is the heiress to the riches of a Czech noble family—the Hajns. Petr, a social climber marries her, ignoring some shady goings-on—in particular, an insane uncle who prowls the mansion believing himself invisible, a peccadillo the family indulges. The uncle’s stalking every corner of the house, popping out of cupboards and out from behind curtains slowly takes its toll on the young bride.
