Blake's 7

- Season 1

(1978)

Former resistance leader Roj Blake witnesses a massacre and is subsequently framed for a series of fictional crimes by the totalitarian Federation.

Blake attempts to take over the prison transport ship London with help from Kerr Avon and Jenna Stannis. When this fails, Blake, Jenna and Avon are sent to investigate an abandoned alien spaceship, where Blake grabs the chance to take control of that ship and escape.

Blake, Avon and Jenna follow the transport ship London to the Federation prison planet Cygnus Alpha where Blake teleports to the surface to free the prisoners. But the planet's supreme ruler Vargas wants to take over the Liberator in his goal of total power and conquest of the galaxy.

Blake picks up an unidentified space projectile en route to an attack on Saurian Major, accidentally allowing three dangerous aliens aboard the Liberator.

Cally comes under the influence of an alien intelligence from her own people's legends, causing her to sabotage the Liberator. The ship goes off course and becomes ensnared by an organic web that surrounds a remote planet inhabited by a genetically-engineered race and their creators.

Supreme Commander Servalan assigns Federation military officer Space Commander Travis (wounded by Blake) to eliminate Blake and the crew of the Liberator. However, Travis takes Cally captive, when Blake and the crew steal a message decoder from a Federation security base on Centero.

Kendall, the captain of a spaceship whose crewmember has been murdered, offers Blake the location to Destiny if he helps him find the killer on-board the ship.

On a world destroyed by warfare, two powerful aliens force Blake and Travis to fight each other to the death so their ships will survive.

Blake and Jenna teleport down to evacuate a well-known resistance leader named Avalon, only to find that she was captured by the Federation. The Liberator's crew launch a rescue mission, not realizing that Travis is using Avalon as bait.

The Liberator heads for space station XK72 where they seek help from surgeon Professor Kayn, when Gan's limiter implant malfunctions causing Gan to go psychotic and violently attack members of the crew. But Professor Kayn has other plans and he informs the Federation of the crew's presence on-board the space station.

Blake and Jenna set out to convince Sarkoff, the exiled former president of the planet Lindor to return to lead his people, before the Federation assumes control of the planet. However, the Liberator is taken over by a group of bounty hunters known as Amagons.

Approaching Cephlon, the Liberator crew witness a spacecraft crash land on the planet. They rescue a man named Ensor, who was trying to get back to his father on Aristo and arrange for the Federation to purchase something called Orac. He forces Blake and Cally to fly him to Aristo, leaving Avon, Jenna, Gan, and Vila stranded on the radiation-scarred surface of Cephlon.

The crew of the Liberator head to the planet Aristo to deliver medical supplies to the computer scientist Ensor, creator of the mobile super-computer Orac. Blake and Cally require anti-radiation drugs for Avon, Gan, Vila and Jenna who have absorbed radiation on Cephlon. Travis and Servalan have also arrived on Aristo as they intend to claim Orac for themselves.
