He welo 'oihana (Family Business)
-A man is killed on a field that was about to be dug up for construction.
-The 5-0 realize that this field was used as a secret burial ground by the Yakuza, who were eager to retrieve their victims before construction unearthed them.
-When Kono asks Adam about the field, his answer leaves her suspicious. She listens in on a call he makes after she leaves his house.
-Kono traces the call to a warehouse, where she discovers corpses in oil drums, engages in a gun battle with a Yakuza killer, and is shot.
-After hearing of Doris's plan to retrieve the incriminating microfiche, McGarrett demands to come along with her.
-The two break into Tyler Cain's building and grab the microfiche, but an alarm is triggered, and Doris is caught by Cain's henchmen.
-In order to bargain for Doris's release, McGarrett pretends to have destroyed the microfiche. But he later reveals that he employed the slight-of-hand magic that his mother taught him, and actually still has the real microfiche.
