When Edward Sharp, a British electronics expert, resigns from the secret service, John Drake takes his place in an attempt to discover why. He is soon directed to an island known as Shinda Shima, which has been deserted by its inhabitants ever since several mysterious deaths. There he finds the enemy headquartered and delivers them Sharp's smuggled electronics. It soon becomes obvious that they plan to use Sharp's goods to break the United Nation's code. Drake returns from the island and, with help from its former residents, launches an attempt to take back Shinda Shima. Written by Twenty Penguins

A lousy way to end the series.
1 May 2014 | by (Bradenton, Florida) – See all my reviews

This is the final episode of "Secret Agent" and although it and the previous episode are both in color, they are not among the better episodes of the show. In fact, this last one is awfully silly and reminds me of the film "Black Dynamite" when he goes to Kung Fu Island to battle the fiendish Dr. Woo! In this case, Drake takes the place of an electronics expert who is smuggling computer parts into Japan in order to take them to a Dr. No or Blofeld sort of guy in charge of this silly island. Not once did anyone question whether or not Edwards (the smuggler) was known to the baddies--and they most likely would have at least seen pictures of him! And, the episode is filled with all sorts of silliness such as a bunch of guys inexplicably practicing martial arts EVERYWHERE on the island as well as very silly costumes. I particularly liked the lady cutting wood in half using her martial arts skill--as you can SEE where the block of wood had been cut down the middle already! Silly and rather shoddy...and a sign that the series had indeed run its course.
