FROM BACK COVER: Terry and his friends work as a logging team. Each machine has a special job to do. However, some of the machines become careless and cut down trees too close to the river. A thunderstom then causes erosion and the river is filled with mud. The fish in the river will be killed unless the machines quickly repair the damage they have done to the ecology. Terry and the others learn that teamwork and attention to the work plan is necessary to get the job done. They also learn how important it is to protect the ecology.

The Darksmiths have the Eternity Crystal and are eager to finally fulfil their contract with their mysterious client. The Darksmiths have also reprogrammed Gisella, the robotic 'daughter' of Varlos, who now seems to be working for them. The Doctor learns that the Darksmiths are due to hand over the Crystal to their client as a secret rendezvous on present day Earth. Will the Doctor be able to intercept the transaction in time? Or will the Crystal begin a war that will continue for all eternity?
