The Doctor is in a coma and Sarah is held prisoner in the spiders’ larder.
On Metebelis III, the Doctor lingers in a coma. Tommy’s brain is healed when he looks deep into the crystal. Lupton becomes embroiled in a plot led by his spider host against the Eight Leg Queen. The Doctor recovers thanks to a machine Sarah retrieved for him from the TARDIS. In doing so, however, she is captured by the Eight Legs. Thrown into a cell with a man named Sabor, Sarah learns the history of Metebilis 3: the humans are descendants of survivors of a crashed spaceship, and the Eight Legs were common spiders on board that became mutated by radiation from the blue crystals. The Doctor finds a type of stone which nullifies the effects of the Eight Legs’ energy rays, which the humans will use in their rebellion. The Doctor attempts to rescue Sarah Jane, but is captured again by the Eight Legs as well.
