The Five-0 task force investigates the murder by ninefold stabbing of Flippa's friend and fellow ukulele band member Luka Palakiko, a gentle idealist and social worker specialized in LGBT youth. Only his minivan was stolen, without valuable cargo. Suspect Connor Russell, a white supremacist, released from prison four months ago, is preparing a bombing, improvising explosives from fertilizer. Steve's team must follow his bloody trail before he can strike, seeking clues from his seemingly converted former cellmate Roger Barton. Grover confides he once dealt with a similar situation in Chicago.
