Hawai 5-0: Just Lucky, I Guess

SINOPSIS

A businessman at a convention in Honolulu decides to indulge himself just a little bit more and plans a one-night stand with a prostitute. When he gets to her apartment, he hears a knock on the door and is told to hide on the terrace. The woman's new guest is a brutal mobster who throws her off the balcony to her death. The businessman has a Hobson's choice of reporting the crime and facing repercussions from his Kiwanish-like home town, not reporting it and having a guilty conscience, or what actually happens -- he doesn't report it, but the mobster's goons figure out there was a witness to the crime and go after him anyway. Will the businessman 'fess up to his indiscretion (pretty rank even now, think about what it was in 1969) or face getting blown away by a shotgun in a parking garage (which is just what happens at the two-thirds mark of the show; they miss but plan to try again)?
