"Requiem for Frank Lee Smith" traces the case of a Florida man who was exonerated of a crime he didn't commit---10 months after he died in prison. Smith was convicted of the 1985 rape and murder of an 8-year-old girl largely on the testimony of one witness, who later changed her story and became an ardent Smith defender. As filmmaker Ofra Bikel shows, this didn't sway prosecutors, who also fought DNA testing. When they relented, in 2000, Smith was cleared. But it was too late.
