Following Lupton, Sarah is accidentally transported to Metebelis 3 where she is captured.
Lupton re-appears at the meditation center, secretly observed by the simple-minded handyman Tommy, who later steals the crystal to add to his collection of “pretties”. The Doctor and Sarah Jane investigate the meditation center. Exploring the basement Sarah steps on Lupton’s mandala and is transported to Metebelis III, where a small group of humans are held in bondage by the giant spiders, who refer to themselves as the Eight Legs. The Doctor follows in his TARDIS to rescue Sarah Jane, but is incapacitated by the Eight Legs’ human guards.
