Responding to multiple maydays, the TARDIS lands on the planet of Death’s Deal, but the distress calls are old, the final echoes of terrified lost souls. This is an exotic world of lethal creatures, nicknamed The Deadliest Planet in the Galaxy, and only the brave, foolhardy or greedy would ever dare to visit. Finding themselves stranded among a motley bunch of space tourists, the Doctor and Donna must lead a struggle for survival against the frenzied wildlife as they slowly realise that other members of the group have very different agendas.
The TARDIS touches down on Nadurniss, a planet under quarantine. A joint Nadurni/human mission has recently landed on the planet to survey it for possible re-colonisation. Two millennia have passed since the Nadurni Empire fell at the end of the Prokarian War, and Nadurniss seems to be a lifeless, barren world - but a mysterious illness is infecting the Nadurni, and now the whole team is in danger.
"Actually a story"
The Amazon rainforest, 1827. The Doctor, Amy and Rory arrive in the jungle near a hurriedly abandoned campsite, where they are surrounded by hungry black caiman - huge lizards. Only the arrival of a man with a rifle sees off the giant beasts. Oliver Blazington has come to the forest to bag big game, and his companion Garrett is a naturalist, collecting exotic creatures for London Zoo. But the Doctor soon discovers that another very different hunter is stalking the Amazon.
