Mr. Donovan was fatally shot at home, where his teen daughter Kelly was apparently abducted by her illicit boyfriend, ex juvenile con and abused foster circuit orphan Tommy Fa'aloa, whose garage employer Gary 'Aikapu believes he's a good kid now. The teens are spotted in stolen cars, even shooting a defensive owner and robbing a store, but Five-O works out only slowly the devious plot of a psychotic killer. Danny can't accept or stop his mother dating around, even seeing an attorney to file for divorce, and arranges an atypically expensive surprise, the point being a special guest. Steve's efforts to send helpful but undesired housemate Jerry back home suffer frustrations, but he actually comes up with a priceless clue to missing mother Doris "Shelbourne"'s whereabouts, which Steve confronts the CIA with.
