Another creepy nautical story from the 1950s "One Step Beyond" TV series. The story is supposedly based on fact, but IMO only loosely. I won't give away the plot, except to say it involves a Nazi official escaping from Germany by submarine at the end of WW II.

The wreckage of a German sub was found off the coast of Argentina in 2015. http://thescuttlefish.com/2015/12/a-...0-years-later/
Several thousand Nazis are known to have escaped to South America, so it is not inconceivable that some traveled by submarine.

The sub in the TV show is identified as U-147. However, the real U-147 was sunk by British warships in 1941. Enjoy the show!
