synopsis
In the conclusion of the six-part story "The Sea Devils," the Doctor (Jon Pertwee) has apparently smashed the efforts by the reptilian Sea Devils to destroy mankind. This, however, does not entirely eliminate the perpetrator of the present crisis, the Doctor's old nemesis the Master (Roger Delgado). Nor is the Doctor able to prevent mankind from getting itself into future scrapes of this nature! Originally shown on March 25, 1972, "The Sea Devils, Episode 4" was written by Malcolm Hulke.
