Doctor Who - Wooden Heart.rar

The Doctor and Martha arrive on the Castor, an abandoned prison ship floating in space. Whilst exploring they find a fully populated village and forest, whose inhabitants appear to be unaware of the spaceship outside, and whose children are mysteriously disappearing. Later, The Doctor and Martha find a creature from another dimension, who, because of its telepathic powers, was used to remove the evil from prisoners in the Castor. To keep itself sane, it expelled the evil, creating a separate being which killed the crew. The telepathic creature then created the forest and village in an attempt to balance itself with goodness, but, due to low power supplies, it is having to remove small parts of the 'program', such as children, to conserve power. The Doctor offers to pilot the ship closer to a sun to give the creature more power to run the program, and a woman from the village absorbs the evil into her body, before exiling herself, so she can learn to control it. The Doctor and Martha then leave the creature to maintain the forest world.
