It's Indonesia in 1883. The Doctor and Rose escape from being tied to a post by the local islanders. The islanders spoke about Men of Flames who are destroying their land. Racing through the jungle, they hide behind a waterfall. It leads underground where they find the Chalderans (a silicon-based, flame-red, horned lifeform, with an incredibly high body temperaure) who surround the Doctor and Rose and capture them. They torture the pair by hanging them upside down for an undetermined period of time, it is here that the Doctor reveals to Rose that they mine planets for lava leaving them totally dead.
