Blake’s 7 is about seven very different individuals with one common connection. They are all escaped prisoners sentenced to live out the rest of their lives on Cygnus Alpha, a barren and sparsely populated prison planet far from Earth, by a corrupt totalitarian government known as the Terran Federation.
Blake, a former resistance leader who had his memories suppressed by the Federation, must now try to hold together his assorted crew of criminals and others. They have control over a very powerful, but mysterious spaceship they call the Liberator. Together they try to bring down the corrupt and tyrannical Federation.
His initial crew consists of Kerr Avon, the master computer expert and embezzler, Jenna Stannis, a smuggler, pirate and expert pilot, Vila Restal, an adept thief with an amazing ability to pick all locks, Olag Gan, a murderer who now has an emotion inhibitor chip implanted in his brain, which limits his ability to become violent.
Blake is later joined by Cally, an Auronar and the lone survivor of her planet’s resistance force, who also has the added ability of being a telepath.
During their adventures, some of the crew is lost, and others are recruited. Some of the newer members include Del Tarrant, a former Federation Officer, who now has a death sentence on his head for piracy, Soolin, whose past is clouded in mystery, but who is an weapons expert, and Dayna, also a weapons expert, who is the daughter of a famous former rebellion leader that went into seclusion before his death.
The non-human members of the crew are Zen, the Liberator’s main computer interface, and Orac, the most sophisticated and valuable computer known to exist
Blake and his crew are relentlessly pursued by the Federation’s Supreme Commander, Servalan, and her handpicked Federation Officer, Space Commander Travis, assigned to find and kill Blake and recover the Liberator as well as Orac by any means necessary.
The crew reluctantly decides to destroy their base, as they must assume Zukan has given up its location to the Federation. They must also now find a new figurehead to lead their resistance struggle against the Federation, now that their earlier plans for a figurehead have failed. Avon tells the team that thinks he knows where he thinks Blake has been hiding, and they should seek him out as their new rebel leader. The crew is dismayed that Avon has kept the information of Blake’s possible location a secret from them but agrees to seek him out.
It seems Blake is working as a bounty hunter on a once lawless planet now transitioning to a law biding society. However, Scorpio
is shot down by the planet’s planetary defenses. Everyone but Tarrant is able to teleport off the ship before it crashes, leaving Tarrant barely alive and the crew scattered across the surface.
Now they find Blake is chasing them all down for the bounty on their heads. But does Blake really have a secret agenda behind his current professional persona as a bounty hunter?
