Vicious Circle

Polly lives alone in a large house. One evening, she invites an elderly woman inside — the woman seems disoriented and unable to find her way home. After asking Polly about her personal life, the stranger gives her a strange black box and tells her that she will die tonight. Polly throws the woman out, but soon discovers that it is impossible to get rid of the mysterious box. It demands that she place three things inside: something she hates, something she needs, and something she loves most of all.
