Hawaii Five-O

Season 12

TV-PG

Five-0 was a special state police unit answering only to the Governor of Hawaii. It worked with Honolulu police to fight the underworld in the island state. Sooner or later virtually all the bad guys heard Steve McGarrett grunt "Book 'em, Danno!" though chief bad guy Wo Fat was caught after MacArthur left the series.
