Plot
The Tardis lands and the Doctor and Yasmin step out of it. The Doctor welcomes her to Gaia-12, a planet known for its lush greenary and beautiful wildlife. Yasmin points out the beautiful flowers and is amazed by the colourful wildflowers and cute animals. As the duo walk deeper into the vegetation, they enter a town known as "Terra", a town that has been entirely out of huts and hollowed out trees. As Yasmin is admiring the view of the forrest, a scream is heard and the roar of a wild animal but The Doctor is able to scare it off. The frantic alien thanks the doctor and calls herself "Leveret" and admits that most call her "Lev" for short.

Lev explains that the wildlife have been acting strange lately as they had been trying to take refuge in their village despite the population trying to scare them away. They did send people to look but none of them returned. The Doctor, curious about this mystery, offers to go investigate with Yasmin. While travelling to the depths of the jungle, Yasmin tries to blame the inhabitants of Terra for drving away the wildlife but the Doctor tells her that Terra is the only town in the area and the planet is big enough for the wildlife to migrate, meaning that someone or something is driving them back to their original habitat.

In the depths of the woods, a robot and his wife are also investigating the forrest and the two briefly talking about their engagement until the robot is suddenly shot in the head and killed instantly. The woman runs away screaming and runs into both the Doctor and Yasmin. The woman calls herself "Taura" and tells them that they need to get out of the woods, which they suddenly do. In the distance, a man holding a rifle points a camera at the Doctor, Taura, and Yasmin as he makes a curious face before informing someone on the radio about what just happened.

Back at Terra, Taura recounts the death of her husband and the mayor Terra explains that it might have been one of the hunters he sent to the jungle and husband may have just been shot by accident. The Doctor and Yasmin are quick to blame Terra driving away the wildlife but the mayor defends his actions by saying that they shouldn't pass judgement until they find the killer, something that leaves Yasmin wary of the mayor. Returning to the crime scene, the trio discover that the body has been removed and Yasmin runs ahead to follow the trail, as the Doctor is yelling at her to come back. Taura reaches Yasmin first and tries talking her down as she doesn't want to be responsible for another death since she was the one who brought her husband to Gaia-12 in the first place.

As the Doctor catches up with the two, Taura notices a lazer and realises that it's from a lazer sight. Before the unseen attacker is about to shoot Yasmin, Taura pulls her out of the way but accidentally gets in the way and is shot and disintegrated in the process. Horrified by the death of Taura, Yasmin and the Doctor run back to Terra but are quickly ambushed by 3 hunters with the fourth hunter complaining that he had put the damage output too high and killed Taura too quickly. Before the Doctor is able to ask any questions, she and Yasmin are knocked out.

Waking up in the hunters base, Yasmin finds out that both her and the Doctor have collars on them and are sitting in front of a man sharpening his weapon. The leader comes in and scans Yasmin, identifying her as human and only worthy of target practice. The Doctor is scanned next and the leader is astonished when he learns that he's standing in front of a time lord and marks her as high priority game. The leader calls himself "Vulpes" and the Doctor tries to intimidate him by calling herself the Doctor but he quickly laughs off the threat. Vulpes explains that he knows who is the Doctor and remembered her more as a man as she ruined his life on Villengard when one of her incarnations blew up the 13 weapons factories and put him out of work.
