With the Daleks distracted by the aftermath of the rust plague, the Monstrons land on Skaro inside a dormant volcano without meeting any resistance. They are detected, however, and a Dalek is dispatched to investigate on a hoverbout. The Monstrons' Engibrain soldiers freeze it with liquid air. Two more Daleks go to investigate but are killed when they come in contact with the Monstons' force field. They then launch an attack on the Dalek City, beginning with a bombardment before using their Anti-Visibility Thruster to blind the Daleks with thick layers of fog. The Daleks are forced to seal themselves inside their City against the fog. The Engibrains are sent fourth to raze the City. The Dalek Emperor fears the Daleks are powerless to repel the attack, then the roof collapses. The Monstrons seal the City with liquid metal so they may take over Skaro.
Trapped in the City, the Daleks fear they are without a leader but they soon find the Emperor has survived in an old watercourse connecting the City with the Lake of Mutations. The Emperor is threatened by a giant electric eel, but is rescued by some Daleks who sacrifice their casing's power to power their magnet. They stun the eel so they can use it to power their equipment.
As the Monstrons celebrate, their captive Dalek heats its casing to free itself from the ice, believing itself to be the last of its race. It fights its way off the Monstron ship, blasting apart the Engibrain soldiers. The Monstons push it overboard and it falls towards the volcano. As its last act, the Dalek fires its weapon at the lava, agitating the volcano. The Emperor and a group of Daleks emerge from a cave leading back to the City in time to witness the volcano erupt and take the Monstrons with it. The Emperor decrees that although they may never know what set the volcano off, the Daleks must now look forward and rebuild the City and protect it from any future invasions.
- The Daleks use a magnetiser to raise the Emperor Dalek from the watercourse.
