The Xenon base security systems have locked down the Scorpio, effectively stranding our heroes. The computerized lock leading to the launch silo can only be opened by Avon, who has his hands full after becoming enmeshed in a war between the male Hommiks and the female Seskas. And if that wasn't bad enough, there's a nuclear weapon counting down inside the launch silo... Written by Christopher M. Buckey

Did You Know?


The teleport system attached to Scorpio and Xenon Base is used for the first time in this episode, which also sees the first use of the Scorpio teleport bracelets (although Avon only uses one as a communicator and none of the crew are actually wearing them when they teleport aboard). See more »


Gunn-Sar: What's the tally of challenges?
Cato: Twenty-five dead and one missing, sir.
Gunn-Sar: Oh, come on, Cato. Don't quibble. Marquin fell backwards off the cliff.
Cato: Yes, sir.
Gunn-Sar: So he's dead. Like, you can't say someone's missing as such. Not when they've taken a dive into a bottomless gorge.
Cato: No sir.
Gunn-Sar: So, it's twenty-six dead.
Cato: The council ruled it was twenty-five, sir, and one missing.
Gunn-Sar: [unperturbed] Twenty-five men lie dead who tried to stand against me. And one, if he's not still falling, is no more than a greasy spot ...

Not A Powerful Episode Of The Show
31 March 2013 | by Theo RobertsonSee all my reviews

With Dorian dead the former crew of The Liberator find themselves trapped in his base . Avon manages to reach the surface of the Planet Xenon where finds a war taking place between a female tribe calling themselves the Seska and a male tribe called The Hommiks

A very average episode featuring once again the protagonists caught between a war of primitive tribes . There is a vaguely logical reason for there being so many planets in the BLAKES 7 being populated by barbarians and that is the planets are abandoned by the Terran Federation and the inhabitants of these worlds find their societies progressing backwards

Regardless of the writer no one seems to be able to make these backward societies interesting in anyway , they're just basic one dimensional characters who chase the heroes while spouting cod dialogue . Ben Steed isn't a great writer but his previous two contributions for series three were outrageous enough to stick in the memory . This episode isn't even outrageous , just very bland
