We left Bob and Lois stripping for their lives in the cracked diving bell.

Luckily, the water stops coming in. Maybe they used up the entire ocean.

The blonde chick decides we’ve all seen more than enough fighting for one outbreak and ends matters by hitting a man with a big stick. You go grrl.

But the baddies have a gun and take Speedy hostage to ensure their safe escape. Their plan being to arrive, start a fight and leave as quickly as possible. Nice plan.

The diving bell is hoisted up to safety.

Scott helps his soggy daughter out and all is well as we fade to black.

Meanwhile, Dr Satan is fuming in his new office.

He’s angry because his mechanical man won’t work without Scott’s remote control device. I know you know that and I know that but the serial is telling us again. Luckily, one of his henchmen makes an astonishingly clever suggestion. If Scott is the only man who can make remote control devices and the remote control devices he’d built have been destroyed, why not capture Scott and force him to make a new one. Dr Satan smiles warmly.

Speed – captured by the baddies – has been fitted with a control vest. It has turned him into a zombie. Which is a new mode not seen before.

Their fiendish plan is to use their new, secret ally to trick Scott into falling into a trap. There is literally no way Bob or Scott or the two girls will be able to tell that Speed is under Dr Satan’s control.

Satan speaks to Scott via the magical tele-vest.

He tells them that the vest is also a bomb and that he’ll destroy the house if Scott doesn’t obey him. Luckily, Bob spots that something is amiss and hides in the doorway.

Bob gets word to Scott – he’s got a plan. Well, sort of a plan. It’s not very super-heroic but, dammit, it might work.

Bob phones the police as promised.

He tells the police chief to shut off the city’s power so Dr Satan’s control panel won’t work. The police chief says that is a silly idea – think of people trapped in elevators. But Bob says think of the whole country if Dr Satan succeeds. The police chief agrees.

Scott tries to procrastinate but Dr Satan becomes agitated.

Bob follows Scott and Speedy out of the house. He checks his watch. It is still there.

The lights go out and Dr Satan is plunged into darkness.

Bob takes the chance to rescue Speed. He’s having awful difficulty. It’s almost as if he’d never removed a gentleman’s bra before.

He tosses the deadly harness away and it explodes.

But Dr Satan has a back up plan – some men arrive and take charge.

A fight breaks out.

Bob is left laying while Scott is taken away by the hoodlums.

The baddies drive away but Bob gets a lucky shot in and pops the car’s petrol tank. The escaping car leaves a trail of fuel for Bob to follow and the chase is on.

Here’s something you don’t see often enough – a car chase where one car stops part way through to fill up at a petrol station. I think it adds authenticity to the play.

They realise their tank has been shot and steal the petrol man’s truck.

Bob finds out about the petrol truck and goes in pursuit of it.

While driving at high speed and for no reason what so ever he decides to put on his tatty Copperhead mask.

The hoodlums decide to give the Copperhead a taste of his own medicine by pouring the truck’s content on the road behind them.

And setting it on fire.

The oncoming line of flame is quite impressive really...

...as it rushes closer and closer to our unsuspecting hero.

Now he suspects.

Didn’t Duran Duran sing about driving into the fire in "A View to a Kill"?

His car explodes and he dies. Next week – the real Superman apparently.
