The two-part TV movie Cruel Doubt was based on a true story, as elucidated in book form by Joe McGinniss. In part one, aired May 17, 1992, Wealthy North Carolinian Blythe Danner discovers that her own son Matt McGrath was involved in a robbery-assault in their home, in which her husband was killed. The story was resolved in part two, which debuted May 19, 1992. As the courtroom trial wears on, flashbacks reveal the extent of McGrath's involvement in the crime, as well as the depths of his mental illness. And for a brief period, there's a slim possibility that the evidence is all wrong, and that McGrath is innocent. The boy's sister is played by Gwyneth Paltrow, real-life daughter of Blythe Danner. ~ Hal Erickson, Rovi
