The culmination of the Key to Time series. The Doctor and Romana search for the last shard of the Key while simultaneously trying to prevent planetary destruction. Doctor Who has always liked talking about violence begets violence, as in this story. There's a cool twist near the end--not everything (aka, The Guardians) are as they seem. ( )

Dicks doesn't add much to what we saw on screen (with of course the added constraint of cutting six episodes down to Target size) and the weaknesses of the plot are consequently more visible.
