A wealthy woman who's raised a nephew in luxury has tolerated the insolent young man long enough. She informs the ingrate that she's changing her will to remove him as sole heir to her estate. Before she can act, he intends to exploit her heart condition and pin the murder on "the monster", a crazed killer roaming the countryside. Richard doesn't realize that the aunt is already anticipating his scheme.

Constance knows that her much younger husband, Evan, is having an affair with her nurse, and that he's hastily stashed her in the closet. That why she demands that he immediately brick up it up. Not wanting to lose out on his rich wife's money, he does as she says. Constance thinks the nasty little problem is behind them until the supposedly dead nurse starts appearing around the house.
