The basic story is this. Earth is testing a new Star Cruiser, the SK Woltemade, that has a powerful weapon.
The Krokons are still intent on gaining inroads against Earth.
Buks de la Rey is assigned to personally deliver orders to the Captain of the Woltemade because Professor Zed thinks communications lines are being spied upon. We are introduced to a robot named Pikkie who insists he should accompany De la rey as Lieutenant Buys has come down with Mars Flu. De la Rey tells Pikkie to stay on Earth.
The Krokon Prince goes to that fixer of all things, the slimy Gorman. In exchange for some concessions (as usual!), Gorman agrees to plant a saboteur on the Woltemade, to cause it to plunge towards a nearby star. When the crew have been overcome by the heat, the Krokons can move in and tow the ship away to disassemble it for its secrets.
Pikkie stows away on De la Rey’s ship against orders. Also on board was the saboteur! In a neat little twist later on, the stowaway Pikkie kills the stowaway Saboteur.
Pikkie also winds up doing a spacewalk to save the life of Buks de la Rey.
Now onto over one hundred screensnaps!
