The crew of HMS Camden Lock start negotiations with various alien civilisations to sell blocks of the Peterborough Enterprise Zone. When things fail the first time, Space Force demands that Commander Henderson and his crew have to find another buyer within a week. The task doesn't get easier with an alien killer machine on board and the navigation system dropping out.

Vine buys a planet while Teal contrives to be alone with Henderson at the officer's ball.

Henderson is invited to join Britains premier space-o-batics team (a Red Arrows for space) led by Squadron Leader Mason, who twenty years ago had a fling with Teal. 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.

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.

Henderson, Teal and York try to make first contact with the Queppu but are instead greeted by crossbow fire and are accused of being rebels. Meanwhile Jeffers, left in command of the ship, enters into a space race.

Clare Winchester, a record-breaking British space-sailer, has been driven a bit mad on her latest solo expedition when she comes across the slightly more mad crew of HMS Camden Lock.

Henderson, miffed at being usurped by the Americans negotiating peace between two alien races, takes matters into his own hands with explosive consequences.

The crew of HMS Camden Lock are subjected to an extremely strict assessment test causing Henderson to seek the solitude of his cabin leaving York in command.

York is sacked from Space Force after footage of him beating up an innocent alien ends up on the news. Teal is delighted to be left in charge of the ship in the officer's absence - but she faces a tough challenge when the team discover the Red Shiny Robots of Vortis are about to attack.

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 the Queppu ready for revenge. After narrowly 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.

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...

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 a desperate race against time to find the mole before Earth is destroyed.
