It was one where a gang of Five-O doppelgangers try to con a contractor and his beautiful wife out of a lot of money. Jimmy MacArthur plays in the ep Danno Williams and his doppelganger. Until the last scene where an extra who is obviously not MacArthur plays the Danno doppelganger. Dramatic license on the audience part is pretending that they do not notice the man is,again, obviously not MacArthur. I believe I wrote about dramatic license before earlier I my reviews on this website. Cannot recall just where as I have written so many.
