In Martha Moxley's Greenwich, Connecticut neighborhood, they called the night before Halloween Mischief Night. It would be that night in 1975 that 15-year-old Martha Moxley would take her final breath and with it would begin a 43-year-long battle to bring her killer to justice. This documentary profiles the 1975 murder of 15 year old Martha Moxley in the rich and well to do gated community of Greenwich Village, CT. Moxely was brutally beaten to death with a golf club on the eve of Halloween in 1975.
