The scene is the West Barrington Institute for Women, where warden Elizabeth Gates (Vera Miles) invites Jessica (Angela Lansbury) to lecture on creative writing. Of course, wherever Jessica goes, murder follows, and this time the victim is the prison's doctor Irene Matthews (Janet McLachlan). Believing that an innocent woman has been accused of the crime, the inmates stage a riot, taking several hostages--including Jessica--in the process. In order to save Warden Gates from being killed in the mistaken belief that she is the "real" culprit, Jessica races against time to solve the murder herself. This is the only Murder She Wrote episode to boast an all-female cast. ~ Hal Erickson, Rovi
