Havaí 5.0: Deathwatch

SINOPSE

An assistant district attorney is killed when he finds a ''box man'' i.e. safecracker rifling through the attorney's office on a Sunday. The assistant DA was preparing to prosecute Matsukino, a local mobster. The key piece of evidence, a handgun, is now missing. McGarrett brings in Matsukino and his right-hand man, Cardonus. McGarrett does a bit of psychological game playing by letting Matsukino go and keeping Cardonus in the lawman's office. The Five-O leader reminds Cardonus that Matsukino doesn't like to leave loose ends. After Cardonus is released, his car blows up. Cardonus, knowing that Matsukino wants him dead, goes to Five-O. McGarrett wants Cardonus to testify at the upcoming trial. The question is whether Five-O can keep Cardonus alive to make the court date.
