The Doctor's legendary regeneration may finally have failed him! His trusted assistants Tegan and Nyssa try to nurse him back to health on the tranquil planet of Castrovalva. But things may not be as peaceful as they seem. What is really going on in Castrovalva? What has happened to Adric? And more importantly, where is the Master? Doctor Who must discover the answers, even as he struggles to regain his strength!
This historic, four part adventure marks the debut of the Peter Davison era for Doctor Who.
