Publisher's summary
The TARDIS arrives in alien woodlands, where a small group of humans hold tight against the menace of the Takers — strange creatures who come by night to spirit away members of their settlement.

But if there's one thing that the inhabitants of Purity Bay fear more than the Takers, it's the dirt and disease spread by strangers. Strangers like the Doctor, Tegan, Turlough and Nyssa...

The fanatical Sister Mertil and her hygiene-obsessed acolytes are victims of a terrible corruption — but not in the way they think. Only the whispering forest knows the truth...

Part one
Set to seek out mentions of Richter's Syndrome so that Nyssa's cure can be tested, the TARDIS lands on Chodor and the Doctor and Tegan go to investigate the cry of a man being taken deeper into the forest. They are taken captive by Seksa and taken to Purity Bay, learning on the way about how the Takers kidnap those who become frail and that Seksa's ailing father, Anulf, is missing.

Turlough and Nyssa, having fallen behind after leaving the TARDIS, run away from whispers which Nyssa feels being pushed into her mind by Shades. Because of Turlough's red hair, Mertil, Seska's stepmother, believes that he is a Taker and tries to capture him, but he and Nyssa run and are forced to wade and swim across a stinking river. Mertil's people hit Turlough with a stone and Nyssa gets his unconscious body to safety.

Impressed by the Doctor's title, Seksa decides to introduce him and Tegan to her germ-obsessed people as their saviours. The two of them enter the rest centre, the guards of which were apparently drugged by the Takers, and see advanced technology on the walls. Mertil finds them before Seksa is ready and orders Jestan to kill the Doctor by repeatedly shocking him with a Cardax defibrillator.

Part two
By threatening to cough over the two sedated guards, Tegan gets Jestan to stop and Seska speaks in her and the Doctor's defence when she arrives. The two travellers enter the decontamination chamber as a show of good faith, but Tegan collapses and they are taken to the rest centre where the Doctor learns that the parts of the spaceship that the people did not use to build their home are kept at the Ghost Place.

Turlough and Nyssa come across the remains of a Taker, an android, and use its luminescent orange cap to find their way in a nearby cave home to other such androids. They run from the Takers when they present hypodermic needles and use the broken one to pass through a force field into a tunnel from which Nyssa temporarily teleports, revealing how the Takers get around.

The Doctor goes to the Ghost Place with Hervey and Jestan, whom Seska wants to keep away from Mertil given their connection. The Ghost Place is said to be home to the Shades, believed to be the unclean dead, and the Doctor realises that the ship is a hospital, indicating that the people of Purity Bay are descended from the patients. Jestan breaks Hervey's neck, planning on framing the Doctor to convince the people to execute him.

Part three
Mertil reveals that she pushed Seksa's mother from a cliff as part of her plan to become leader of Purity Bay before having Antan shoot Seksa. She blames the Doctor and Tegan for Seksa's injury and rouses up the people for a lynching, but Nyssa interrupts and presents them with the destroyed Taker in an attempt to earn their trust. When the Takers arrive and carry Tegan away in error, Turlough impersonates a Shade to frighten the people and the Doctor, having knocked out Jestan, uses a device in the rest centre to put them all to sleep.

The Doctor, Turlough, Nyssa and the injured Seksa head to the caves to find Tegan and Anulf. From the Taker and its brief possession by a Shade, the Doctor deduces that the Shades are the echoes of forty-four patients killed in an energy blast intended to euthanise them due to them suffering from Richter's Syndrome. Mertil and the crowd catch up with them and intend to kill them whilst, in the Takers' sterile environment where their patients live, Tegan tries to convince Anulf to leave with her and learns that his wife is still alive. The Doctor, Turlough, Nyssa and Seksa pass through the force field.
