Jessica (Angela Lansbury) is appointed foreman of the jury in an apparently "open and shut" murder trial. The accused claims that he killed the victim in self-defense, when said victim found the accused in bed with his wife. Half of the jury is for conviction, half for acquittal; as for Jessica, she is convinced that there is more to the case than meets the eye. Indeed, she believes that more than one murder is in play here--and as usual, she's right!
