SUMMARY:
The Doctor, Amy and Rory arrive in Wales in 2020, where Dr. Nasreen Chaudhry ( Meera Syal ) and Tony Mack ( Robert Pugh ) are drilling into the ground for a mining experiment. Mack's son-in-law Mo (Alun Raglan) had been dragged underground, and the same fate befalls Amy. The Doctor discovers that the reptilian humanoid Silurians , disturbed by the drilling project, reach the surface and kidnap Mo's son Elliot (Samuel Davies). Rory and the Doctor capture Alaya ( Neve McIntosh ), a Silurian which has infected Tony with her venomous tongue. As a Silurian is about to vivisect Amy (as he had done to Mo), the Doctor takes Nasreen underground on the TARDIS and they discover an immense Silurian civilisation.
