Gerry Anderson's U.F.O. Wiki

"Mindbender" is an instalment of UFO: The Series that actually goes behind the scenes of the programme through the courtesy of a rock found on the surface of Luna, presumably of alien origin, that distorts the perceptions of reality of whoever is holding it. This is because some of the sets Edward Straker hallucinates when he holds the rock were actual sets used in the production of UFO: The Series.


When a UFO self destructs close to Moonbase, interceptor pilots Conroy and Dale are sent out to investigate. They find nothing of interest but one pilot, Conroy, finds a curious diamond-like moon rock that he keeps as a souvenir.

However, when Conroy re-enters the Control Sphere on Moonbase he hallucinates that there are three Mexican bandits there. He starts to fight the bandits unaware he is actually fighting Nina Barry and other Moonbase operatives. Barry sets off an alarm but Conroy shoots and kills Dale. A search is ordered and Conroy is killed in the ensuing gun fight.

Straker investigates Conroy's strange behaviour but only find that the pilot had an interest in the Old West. Conroy's personal effects are returned to SHADO headquarters where they are sorted by Capt. James. James also falls under the control of the moon rock and believes SHADO HQ has been invaded by aliens and starts shooting everyone he sees. He is killed after taking Col. Lake hostage.

The moon rock then appears on Straker's desk and he gets into an argument with Henderson. However, a film director shouts 'Cut' and Straker finds himself as an actor on a set. Straker wanders the film sets but manages to stop the hallucinations by throwing the moon rock. The rock caused hallucinations in anyone that touched it.
