Dianna Green is brutally attacked in her own home and her unborn child is killed. After coming out of her coma and regaining her memory, she identifies her husband Kevin Green as the perpetrator and the semen left at the scene matches her husband's blood type. The husband was convicted and spent 16 years in jail proclaiming his innocence. Then, a new DNA test and an innovative computer program lead investigators to question just how accurate the wife's recovered memory really was.
