An episode about a literal Lady Killer, who marries an American Woman in London and the first problem is that the gorgeous Agent 99 from Get Smart would even be interested in such a ferret-faced man who is the star here, and other problems include the TV budget... most British shows save The Sweeney shot on video and looked cheap, and the sets here look like sets from a bad sitcom, which some of the dialogue also mirrors as it's mostly a talky kind of episode...
England always seemed more progressed than America... there are actually nude shots on The Sweeney and British films discussed taboo subjects years before America, but the married couple sleep in separate single beds, which is quite funny and understandable had this been a sitcom in the 1950's but for a 1970's thriller anthology, well...
The entire premise is so unbelievable and the direction is like a security camera pointing at people within bad sets, so... don't think this show's worth checking further into.
