Synopsis

La série se termine par la confrontation finale entre McGarrett et Wo Fat. Trois scientifiques ont disparu. Ils ont une chose en commun : ils ont tous assisté à un symposium qui a discuté d'un éventuel système spatial de défense laser. McGarrett se fait passer pour un quatrième scientifique, le Dr Elton Raintree, qui a assisté au même rassemblement et est bientôt enlevé. Wo Fat est derrière tout cela et souhaite que les scientifiques terminent leur travail et produisent un tel appareil.
