Entrusted with leading the convoy guarding Britain's new super-weapon, the Camden Lock's position is betrayed. There is a traitor aboard and all the officers are under suspicion. There is desperate race against time to find the mole before Earth is destroyed. Only Vine's new gadget offers any respite from the mounting tension.

The crew discover the Dreamgate, one of the most dangerous devices in the Universe, which gives its owner the power to infiltrate other people's dreams without their knowledge. Henderson and York wander into Vine's dream of a pub in the mid 1990s, but when Vine wakes up they become trapped inside his head. Can the rest of the crew bring them back from 1995?

York is sacked from Space Force after a short trial in the ship's Justice Room and Teal is promoted in his place and left in charge of the ship. Unfortunately, the Red Shiny Robots of Vortis are about to attack and harvest the minds of the crew. Will York attempt a daring rescue or can Jeffers figure a way out of danger?

The daughter of the Space Admiral has run away avoiding university and Henderson is ordered to get her back. Meanwhile both Vine and Jeffers have taken a shine to the young student and fight for her heart in the only way they know how - a duel. Arabella steals a shuttle craft and elopes with Jeffers leading them both into mortal danger.

When presented with a mysterious object Henderson can't help but try to return it to its rightful owners despite York's warnings that it's a classic hero trap. The three senior officers find themselves on a forest moon suddenly surrounded by aliens ready for revenge. After narrowly being avoiding destruction last year they have acquired new technology and are ready to strike back by putting Henderson, York and Teal into a reality TV gladiatorial contest.

Henderson is invited to join Britain's premier space-o-batics team (a Red Arrows for space) led by Squadron Leader Mason, who twenty years ago had a fling with Teal. Mason is jealous of Teal's feelings for Henderson and decides to take drastic action. Meanwhile, York reveals the results of his terrifying scientific experiment and Vine has enlisted Jeffers into injuring him in a 'workplace accident' so he can be sent back to Earth.
