| ShortSummary = The Doctor takes Tegan to the village of Little Hodcombe to visit her grandfather. The villagers, led by Sir George Hutchinson, are reenacting events from the English Civil War, including skirmishes which took place near the town. But the recreations have revived the Malus, an alien entity buried beneath a ruined church which feeds on the passions inflamed by war and death. Time is becoming distorted while Hutchinson – who has fallen under the Malus' influence – works to set the creature free, putting Tegan's life at risk in the process.

Before Peri can bid her farewells, Kamelion – once again under the Master's control – takes the TARDIS to the planet Sarn. There his mission is to find the Master, who has been diminished to just inches in height following a mishap with his tissue compression eliminator, and restore him using the healing properties of Sarn's miraculous numismaton flames. But Sarn hides a mysterious connection to Turlough's past – a connection which may prove to be the catalyst in the Master's scheme.
