This is Part 1 of the third episode of the Change of Identity reconstruction of The Savages created by Bruce Robinson. This was likely to have been produced around the year 1997 despite this being difficult to confirm for certain.
The Change of Identity reconstructions were unique, as they contained descriptions of what is going on in the scenes (in yellow text) and captions of character dialogue (in white text). You will need to read the information quickly as it changes very rapidly.
Hope you enjoy this attempt to reconstruct this missing Hartnell story!
