Description: Mr. Pem returns to help Admiral Nelson prevent the Seaview from exploding. Pem transports the submarine to 1780 where they encounter General Benedict Arnold and Major Andre. This was one of the best episodes in the series in my view. It contained some of the silliness that was the trademark of the last two seasons (and that's what we loved about the show anyway!) However, some thought went into it as well. You learn a little about history and until I saw the episode I was unaware of Major John Andre. From reading about him in the encyclopedia I learned that he was purportedly very much like the character as portrayed so well by William Beckley. The closing scene where Kowalski asks Nelson what would be Andre's fate is thoughtful and somewhat moving as well. Wonderful performances by Barry Atwater and the always delightful Henry Jones as the impish Mr. Pem. A blend of both action and historical interest, "No Way Back" closed the classic series on a definite high note.
