This ABC children’s serial starred Gerald Flood as science journalist Mark Bannerman.
In the opening episode, ex-Nazi U-Boat commander Kurt Swendler (Denis Goacher) steals the British atomic-submarine Cyana, but hidden onboard are Bannerman and his youthful photographer assistant Peter Blake (Stewart Guidotti).
Bannerman and Peter are taken to Aegira – an underwater city (hence the series title) – and discover many ‘missing’ scientists working in a laboratory.
Professor Ziebrecken (Aubrey Morris) is working on a plan for the conquest of the seas and “a world free of tension and strife”. Although he claims altruistic motive, Mark Bannerman discovers a stockpile of warheads for nuclear missiles.
