Gerald Flood returned as science journalist Mark Bannerman in this six-part sequel to the 1962 series City Beneath The Sea.
Kurt Swendler (Denis Goacher) escapes the authorities, and in the guise of a showman exhibits the “eighth wonder of the world” Phenicium, a rare metal vital for space research.
Bannerman sets sail for Aegira to look for the important Phenicium deposits but Sir George (Reginald Smith) orders a ship to ram their submarine.
The attempt is unsuccessful and once at Aegira, Peter meets Professor Gordon (Robert James), who is designing a spectroscope camera until it is sabotaged by nasty Dr Deraad (Richard Coleman).
All is revealed in the final episode and the Phenicium is located.
