Ten people are invited for a weekend on an island by a mysterious stranger, but it turns out he isn't present. At dinner a record is played which accuses each one of the guests of having committed a murder. They soon begin to realize a crazed killer is stalking them.

This documentary by Joe Berlinger and Bruce Sinofsky details the murder trial of Delbert Ward. Delbert was a member of a family of four elderly brothers, working as semi-literate farmers and living together in isolation from the rest of society until William's death.
