Episode 80 - Terror of the Zygons

Several off shore oil rigs have been mysteriously destroyed and
UNIT have been dispatched to investigate. Foul play is suspected
but is it industrial sabotage or something more ethereal.


This week, Paddy and Tricia join The Doctor and his companions as
they arrive to the highlands of Scotland to help with the
investigation. Can they discover the cause of the damage whilst
remaining safe from the Terror of the Zygons?
