Evil minds (we want to start a war and emerge the rulers of the world) have devised a way of turning a human being into a walking bomb if they come into contact with radiation.
Nelson been asked to undertake a spying mission in the black sea to ascertain if the Russians have devised a huge new nuclear bomb which could make all other weapons useless (like they do)
The briefing at the beginning feels more like James Bond with Nelson being given secret breathing devices and guns hidden in pocket watches. He also meets a beautiful female Russian which seems to have him grinning. Things quickly turn sour when Nelson is secretly injected with the explosive substance.
After a tense scene avoiding a destroyer the Seaview launches the flying sub and Nelson suited in a blue jump suit prepares to parachute into Russia.
Once down Nelson then changes his appearance to the most unconvincing Russian sailor ever and oddly keeps running into people who speak perfect English.
Soon Nelson is grinning again as he frolics and romps about with the Female Russian spy unaware she's out to finish him.
Back on Seaview Crane has been informed that Nelson has been turned into a walking bomb and before long he's been packed off to Russia with a load of gadgets too. He has orders to save Nelson or kill him if goes near the Nuclear power station to complete his spying mission, which will set off the bomb.
Using speed boat races as a cover Nelson swims underwater to the Nuclear research base, with Crane and a female assistant hot his heels. By this time Crane has discovered the Russian female is a double agent and he is forcing her to help him stop Nelson.
Crane gains entry through the main gate after rather a clumsy way of distracting and knocking out the two guards. He then changes into their uniform.
Nelson emerges from the water after a near miss with a blow torch and nearly kills his little pocket watch gun is broken otherwise a beautiful friendship would of ended there!
Crane explains all and gives Nelson the antidote which happens to work immediately (so handy). Nelson still wants to look at the reactor and heads in.
The base is alerted when Russian guards find one of the main gate guards unconscious spread eagle in full view without his uniform. (No wonder they selected Nelson for the original mission) what was Crane thinking not hiding the guards body?
The group head off and make for the sea not before abandoning the female double agent. Soon they meet up with the flying sub and are back aboard Seaview where Nelson explains there was never any super weapon, the whole thing was an attempt to start a war.
Nothing too exciting here I'm afraid and very little time is spent aboard Seaview.
Its odd seeing Nelson enjoying the company of the Russian female and kissing her. I keep the thinking of the Nelson which would end series four grumpy at times and having to save the world every week from a rubber monster.
Fun to watch an early episode simply because it was early and things were different.
