A prison lifer working in the infirmary as an orderly gets the shock of his life when a dying fellow inmate confesses that he himself committed the murder that the orderly, a businessman on the outside, was convicted of three years earlier. Nobody else heard the confession, and there is no evidence tying the now-dead hit man to the murder. The orderly freaks out and grabs a guard's riot shotgun, tapes it to the throat of the prison doctor and sends out the word -- reopen his case and find the person who ordered the hit, or get the doctor's head on a plate. Skeptical at first, McGarrett soon finds evidence that contradicts statements made at the businessman's trial and renders his "motive" for the murder meaningless. He still doesn't know who could have ordered the hit, though. A professional colleague of suspect, victim and the suspect's lawyer is found to have perjured at the trial -- coached by the lawyer, who DID order the hit.

One of the better ones....
25 February 2010 | by MartinHaferSee all my reviews

This film is actually the second one involving a prisoner taking a hostage and negotiating with McGarrett. And, interestingly, it's also the second one where Al Harrington (who later played the regular cast member 'Ben') was in the prison--but here he is a guard and not a prisoner.

The show begins with a prisoner being brought into the infirmary after being stabbed. Surprisingly, the dying man is being cared for by the man who was sent to prison for murder...a murder the dying man actually committed!! The dying guy admits this to him but dies before anyone else can witness this. Enraged, the innocent man grabs a guard's gun and takes the doctor (look--this actor is Boss Hog from "The Dukes of Hazzard") hostage. When McGarrett arrives shortly afterwords, the prisoner says he'll kill the doctor unless McGarrett personally investigates his three year old case and prove he's innocent.

What follows is a fascinating show--where, despite it being a very cold case, it turns out to have a lot of unexpected twists and turns. Very well written, not a lot of macho histrionics and very good acting all around. See this one.
