The Trial of the Century takes a shocking turn when the defense says Erik and Lyle Menendez killed their parents after years of sexual abuse.

In 1989, 21-year-old Lyle and 18-year-old Erik Menendez walked into their parents' den and killed them. Erik Menendez himself shares in stunning detail the events of the week leading up to the murders and the motive behind the crime that shocked America.

Erik Menendez recalls his mother's decline in the years leading up to the murders and looks on in agony as his brother Lyle testifies, vividly describing the abuse at the hands of their father.

The first trial ends in a stunning surprise verdict. Erik alone takes us inside the prep for his second trial, his unlikely connection with OJ Simpson, and why he alone is left to speak for both the brothers.

After the verdict comes in, at the last minute, Erik Menendez and his brother, Lyle, are sent to separate prisons. Erik marries and begins to mount an appeal. Will his case be given another chance?
