The Doctor, Crystal, Jason and Zog have landed on the leisure world of Krennos. They land outside the dome and have to fight sucking mud and moving trees to get there. While they struggle, the Manager watches them on screen with Susie. They have been investigating disappearances for weeks, and Susie thinks they should investigate. The Manager is too weak to make a decision, so Susie sends two people out. In his office, the Manager, who was using Blade the last time he met the Doctor, makes a decision. He converts himself to one of the plants, and the attack stops.
