With the Cybermen preparing to launch a full attack, the Doctor and his friends must keep the Moonbase and the Gravitron out of their hands until help arrives from Earth.

The TARDIS arrives at a holiday camp company with the crew worried by a prediction of giant crabs and the Doctor becomes interested in the apparent madman Medok's stories of creatures that roam the colony at night.

The Doctor and Polly manage to save Jamie from the Macra and then try to show the Pilot who is really in charge of the colony.

The Doctor and Pinto are captured by the Chameleons but the Doctor manages to use their dependence on their human originals to create dissent in their ranks.

Trying to find the stolen TARDIS, the Second Doctor and Jamie are lured into a trap by the Doctor's old enemies the Daleks.

As part of the Daleks' experiment, the Doctor manipulates Jamie into attempting to rescue Victoria.

Jamie and Kemel team up to try and find Victoria, while the Doctor and the Daleks continue to monitor their progress.
