5D. Doctor Who - The Androids Of Tara

The TARDIS lands on the planet Tara in the continuing quest to assemble the Key to Time. The Doctor insists of fishing, whilst Romana goes off alone to obtain the segment.

Romana finds, and transforms, the fourth segment that was part of a statue. After she has done that she is taken by Count Grendel. He is amazed how similar she is to Princess Strella, and that's when Count Grendel gets an idea inside his head.

Prince Reynart is due to take the throne soon, but he is concerned that he will be assassinated. He has an android duplicate for this eventuality. The Doctor is taken captive by Reynart's men, and asked to repair the android.

Meanwhile Grendel is having android problems of his own. His plan was for the real Strella to marry the Prince, then the Prince would be killed. Grendel would then marry Strella, taking her estates, and she would also be killed. As the real Strella would not co-operate he planned to use an android. But now he has Romana the plan was to change ...
