College professor is sentenced to a maximum security prison for manslaughter. Early made-for-television prison film is well worth seeing despite familiar story line and characters. Impressive direction, cinematic quality acting, good script and not a miscast anywhere. Viewers may also enjoy "Shawshank Redemption" (1995), "Escape From Alcatraz" (1979) and "Runaway Train" (1985). (Rating: A-minus)
