And so we reach the final instalment of what has been a thrilling serial. These last eleven weeks have been spent eagerly looking forward to Saturday morning and a trip to the pictures. But will all turn out for the best or will evil triumph as usual?

Well, we are reminded that Unga Khan is "bent upon conquering the upper world", Sharad "fights futilely to save his people" (which is good considering he’s dead), he’s also referred to as "last of the old time Atlanteans" which sounds like a music hall act, Professor Norton has "regained his mind too late", Billy has reached the sub and "starts for the upper world" and Crash made "one last desperate attempt to defeat the mad tyrant" before being burnt to a cinder in the rocket silo. That’s everyone I think. Well, except for Diana.

Diana – bless her – has spent eleven chapters earning herself this.

We left Crash and the Professor for dead but lo! They’ve fallen through the floor and landed safely below. Huh? Here we see Volkite-Crash as he somehow slides through the ground beneath him.

Crash takes the opportunity to get properly nekkid again before bothering to check whether the unconscious Professor is still with us.

The tower is shaking itself loose of the rock into which it was built. Crash and Norton resolve to stop the tower taking off as it would shatter the roof of Atlantis and flood the place utterly. Khan and the lackey look down upon their handiwork. How utterly evil.

You’ll have to take my word for it but this is the tower taking off.

Oh whoopti-doo (or however you spell it) – the two comedy characters have escaped from the black hats (off screen), made it back to the submarine (off screen) and are preparing for departure (on screen). I had been worrying about them, no I hadn’t.

Diana and Billy are aboard the submarine and Billy explains that he can pilot the sub and follow the tower through the hole in the roof. They’ve obviously given up on trying to save the thousands of Atlanteans who are going to drown to death. Billy does absolutely nothing with any priming powder and yet the sub works fine. That’s one sub plot we can happily (retrospectively) ignore.

It’s another "taking my word for it" as we see the tower rise through the water.

Crash tries to get into Unga Khan’s throne room to use the tele-vision to warn the naval base that a tower is coming up from Atlantis to take over the world. Thank goodness it’s Crash Corrigan – coming from anyone else that would sound silly. There is a guard but Crash deals with him the Corrigan way.

Crash sends his message and an incredulous radio operator writes it down on a pad.

Meanwhile, Khan and the lackey return from the guard room. The lackey either has a new high-tech corset or the continuity man has been snorting priming powder again.

All the professor’s hard work comes to fruition as the tower reaches the surface of the ocean. Unga Khan has reached the upper world at least.

With all the high tech equipment he has at his disposal, Unga Khan’s first instinct is still to look out of his throne room window.

His second act upon the surface of the planet is to blow up a near by sailing ship.

Then they activate the disintegrator and start another earthquake. This is too much for Crash Corrigan and he leaps out of hiding and batters the lackey.

Khan grabs a nearby… thing… and goes to join the manly brawl.

But Crash is too good for the likes of him. He dispatches both of his enemies in one manly swoop. He activates the tele-vision and calls the naval base. But his conversation is overheard by a passing gang of black hats.

They capture Crash but before they kill him Khan intervenes and says to tie him up. Not a wise move, chum. You don’t learn anything.

The submarine reaches the surface and Billy spots Unga Khan’s tower bobbing away in the water.

Hurrah! Here comes the Navy to save the day.

Khan spots the navy on the tele-vision and gives perhaps the most ludicrous order in the history of low budget science fiction action adventure serials.

"Project the invisible wall of atom rays around the tower"

Pah! Khan may have harnessed the power of the atom but we have men with flags. Tremble before our semaphore, Mr Khan.

Crash gives Professor Norton the eye and Norton responds by reaching round and fiddling with Crash’s bonds.

Crash is free~! Naturally, the first thing he does is drop the still-bound Norton down the shaft into the Volkites’ workshop. It can’t be more than a thirty foot drop. Piece of piss for an old man who can’t use his hands.

Crash follows him down and they deactivate all of Khan’s machines. Now the navy’s rockets can reach the tower and do real damage.

The tower is taking quite a battering and Khan throws a hissy fit.

Khan and his lackey decide to cut their losses and escape in the air ship thing. But they find to their horror that Crash has beaten them to it.

He steals a gun from a nearby snoozing Volkite but a well timed bang gives Crash the chance to escape. He and Norton soar clear of the tower.

The Navy finally stop pissing about firing one gun at a time and give the tower everything they’ve got.

Some time later, Professor Norton is in his lab trying to work out how to bring the Volkite back to life. Obviously the secrets of rubbish robot cretins intrigues him.

But Crash has a more pressing task for Professor Norton. He needs him to be a witness at the wedding of Crash Corrigan and Diana the fearless, go-getting newspaper girl.

Awwwwww.

But wait! The Volkite lives. Unga Khan must’ve survived the tower’s destruction and is reasserting his control over his weapons of mass destruc…

…oh no – it’s only Billy playing a prank. B’ohhh.

We end, as we always should, with laughter. Thousands of people died, an entire continent was wiped out, a whole civilisation has been destroyed, several hundred horses have drowned and probably the last all-male society the world will ever see is gone forever but as long as you can see the funny side you will be all right.

And for once Crash lives~!
