Weapon was the third episode of Series B it was first broadcast 23 January 1979. It was the first for this season to feature Servalan and Travis.


From the VHS release:

The battle rages on between the freedom fighters and the Federation as they search for the stolen prototype of Imipak - delayed death at the press of a button. Servalan and Travis have a clone of Blake and they're anticipating the Liberator's every move - can the folk hero escape annihilation this time?

On a deserted planet, two fugitives, Coser and Rashel, fake the crash of their spacecraft. Meanwhile, on the world of the Clonemasters, Travis is confronted by Blake who he promptly shoots dead. However, another Blake then enters. Both are clones created by Clonemaster Fen on Servalan's orders and Travis is angry that she used him to test their plausibility. News reaches them that Coser has fled the Federation's weapons development facility, taking the prototype for the new weapon Imipak with him.

Avon, Gan and Blake plot.

Meanwhile, Blake and Cally have been planning an attack on the weapons development facility without telling the rest of the Liberator crew. Vila is quick to support the plan but Avon announces that Orac has declared the plan suicide. Blake quickly realises this is only because the base is currently on high alert because of Coser's escape. Learning of the theft of Imipak, the crew quickly decide they need to find out what it is.

Servalan hoding imipak with Travis Weapon

Servalan claims Imipak.

Coser is confronted by the clone of Blake and proudly shows him Imipak, his own invention: The target is marked with the gun, making their molecules permanently unstable, which can then be triggered by the control box. The boxes can thus be set up to kill any marked person that comes within range or the targets can be told where the boxes are so they have to stay away. When Servalan and Travis enter, the clone hands Imipak to them. Servalan uses it to kill Coser but the clone Blake prevents her killing Rashel, taking her away and guarding her. Meanwhile, Carnell is brought a report by an officer and notes the man has saved his life.

Blake, Avon and Gan teleport down to the planet. Servalan has Travis surreptitiously mark them with Imipak, then herself marks Travis and a trooper. When Blake's group enter, Servalan demonstrates Imipak by killing the trooper. Blake's party teleport back to the ship and Blake orders Jenna to try and use the planet as a shield. This was Servalan's plan, in order to let the Federation believe Blake has Imipak.

Carnell close up Weapon

Carnell farewell's Servalan.

Servalan tells Travis to trigger Imipak but Rashel and the clone Blake enter, having joined forces, and Rashel reveals she has already marked the pair. Servalan and Travis are forced off the planet: They can't tell the Federation what has happened and, while Rashel and the clone can't leave the planet, they'll never be able to return. Rashel decides to contact Blake to let him know he's safe from Imipak. Back at her base, Servalan finds a farewell message from Carnell, who on learning Coser had taken Rashel, a slave girl, with him realised the plan would fail.

Clone Blake: Thirty-four.
