The Hungry Earth (TV story)

The Hungry Earth was the eighth episode of the fifth series of the revived series of Doctor Who. It was the first part of a two-part story that featured the first televised re-appearance of the Silurians since 1984's Warriors of the Deep.

Synopsis
It’s 2020, and the most ambitious drilling project in history has reached deeper beneath the Earth’s crust than man has ever gone before – but now the ground itself is fighting back. The Doctor, Amy, and Rory arrive in a tiny mining village and find themselves plunged into a battle against a deadly danger from a bygone age.

Plot
In 2020, in the small Welsh village of Cwmtaff, a team led by Dr. Nasreen Chaudhry is attempting the deepest drilling project in history in order to investigate minerals that appeared locally, but otherwise have not been seen on the planet's surface for over twenty million years.

Mo Northover, a night watchman on the project, is present at the drilling site when a strange earthquake strikes. Upon investigating, he discovers a smoking hole in the floor of a store room. Kneeling down next to it, he plunges his hand into the hole, realizing that nothing exists beneath it apart from air. He is promptly dragged beneath the surface despite attempting to escape.

Shortly thereafter, the Doctor arrives in Cwmtaff with Amy and Rory, having promised them a vacation in Rio de Janeiro; however, the TARDIS misnavigated yet again. As they look out across the valley, Amy spots two figures waving at them from the opposite hillside; the Doctor realizes that it is Amy and Rory from the future, coming back to revisit past glories. Though she finds this "interaction" with her future self thrilling, Amy pleads to continue on to their intended destination; however, the Doctor is intrigued by the presence of blue grass in the cemetery where the TARDIS has materialized, as well as the site of the drilling operation in the valley below. He insists that they investigate.

&nbsp While the Doctor and Amy head off to explore, Rory returns Amy's engagement ring to the TARDIS for safekeeping, promising to catch up to them. As he disembarks from the police box, he is stopped by Ambrose Northover, who mistakes him for an investigator that she called down; along with her son Elliot, she explains that local graves have been mysteriously dug up and bodies have disappeared, despite the fact that no disturbance registers from the surface. When Ambrose leaves to get tea, Elliot talks to Rory, who is still baffled and tells him his conclusion is that the bodies are eaten by the graves; he believes this is the answer due to is "Sherlock Holems" audio books, which say whatever is improbable is most likely probable.

At the mine, the Doctor and Amy meet Nasreen and her assistant, Tony Mack, who are investigating the hole in the store room. Checking the readings on Nasreen's computer, the Doctor announces that the Earth is shifting when it shouldn't be; suddenly, another earthquake strikes, causing more holes to appear. As the group rushes to escape, Tony is caught in one of the holes; despite the Doctor's orders that she continue moving, Amy stops and tries to help Tony only to be caught in one of the holes herself. Nasreen and the Doctor double back to help the two; Nasreen succeeds in helping Tony to safety, and the Doctor orders them to shut the drill off while he holds onto Amy. Though he promises not to let go of her, he can't stop her from being pulled under.

When Nasreen and Tony return -- having shut off the drill too late to save Amy -- the trio continues inspecting the Earth. The Doctor deduces that the Earth was bio-programmed to attack whenever it perceived a threat -- namely, Nasreen's drill, which has breached a network of tunnels twenty-one kilometers down. Using her computer, he realizes that transport pods are heading for the surface, and will arrive in twelve minutes. The Doctor, Nasreen, and Tony gather the equipment and make for the church, where they encounter Rory, Ambrose, and Elliot. The unknown attackers create an energy barrier around the town to prevent escape; it also puts them under cover of darkness. Both Ambrose and Rory are furious that their loved ones have been lost, but the Doctor promises to get them back, though he requires their cooperation. The group sets up a network of cameras and security alarms around the church, and cintinues monitoring the pods' ascent via Nasreen's computers. The Doctor, distracted by the impending threat, allows Elliot to leave the safety of the church so that he can return home and collect his headphones.

The attack begins, but the attackers' advanced technology knocks out the camera network, leaving the group blind. Elliot is chased back to the church by a reptilian humanoid creature; it manages to catch up with him before the group can open the door of the church. Ambrose races out into the night, calling out for her son, and is attacked by one of the creatures; when Tony steps in to rescue her, the creature lashes out at him with its venemous tongue. Though they are unable to retrieve Elliot, the Doctor and Rory manage to capture one of the creatures in the back of Ambrose's Meals-on-Wheels van.

Amy awakes beneath the surface to find herself trapped in a clear plastic container. Despite her protests, a shadowy figure appears overhead and activates a control, flooding the container with gas that knocks her out again.

The Doctor and Rory bring the creature to the church cellar and restrain it with chains. The Doctor deduces that the creature is a member of an unknown, three hundred million year old branch of the Silurians, a reptilian race that inhabited Earth before the humans. He confronts the prisoner, a Silurian warrior called Alaya. She explains that the Silurians have been hibernating below Cwmtaff for countless centuries, but their civilization was disturbed by the drill, threatening its safety. The Doctor attempts to negotiate with her, but Alaya declares that the Silurians will wipe humanity off the surface of their planet.

The Doctor returns to the church hall, informing his companions of his intention to travel down beneath the surface and commence negotations while simultaneously rescuing Amy, Mo, and Elliot. Tony insists that they dissect Alaya to learn more about what they are facing, but the Doctor refuses, knowing that if they are to get their loved ones back unharmed, Alaya must be kept alive. He entrusts the humans with this responsibility, paying particular attention to Ambrose, who has opposed his actions thus far. As the Doctor goes out to the TARDIS, Nasreen follows, requesting to go down with him; he reluctantly agrees. Nasreen and Tony share a passionate kiss before she departs.

Below the surface, Amy regains consciosuness once more. She is strapped to a standing medical table in a laboratory; Mo is imprisoned next to her, and warns her of her impending dissection. He reveals a long scar stretching down his chest as evidence of this. Amy begins to scream as a Silurian scientist approaches her with a scalpel.

Tony returns to the church and inspects his wound in a mirror, horrified to realize that the veins around the injury are turning green.

The TARDIS materializes in a cavern deep within the Earth; the Doctor and Nasreen begin exploring the surrounding tunnels in search of the Silurian camp. The Doctor warns Nasreen to expect a small group of perhaps a dozen Silurians; however, she points him to an entire civilization, stretching for miles around.

Continuity

 * In 1984's Frontios "...the earth is hungry" too. There too people were swallowed by the ground.
 * The Silurians have appeared twice in television stories, in 1970's DW: Doctor Who and the Silurians and then alongside the closely-related race Sea Devils in 1984's DW: Warriors of the Deep. The Sea Devils also appeared in 1972's DW: The Sea Devils.

 * DW: The Dæmons also featured a small town cut off from the outside world by an energy barrier.
 * DW: The Green Death was also set in a small Welsh mining village.
