Opening narration
The opening title narration for each episode consists of the following:

This is the year 2020. The place is the Challenger Sea Mount – the top of an underwater mountain, a complex beneath the sea. Two hundred and fifty men, women and children live here, each of them a scientist pioneer. For this is our last frontier – a hostile environment which may hold the key to tomorrow. Each day, these oceanauts meet new challenges as they build their city beneath the sea ... This is Sealab 2020.
Plot

The series took place at Sealab, an underwater research base based on the Challenger Seamount (an underwater mountain), in the year 2020 (48 years in the future at the time of broadcast). Commanded by Captain Michael Murphy, Sealab was home to 250 people, and was dedicated to the exploration of the seas and the protection of marine life.

Among other things, the crew of Sealab faced such challenges as attacks from sharks and giant squids, potential environmental disasters, and threats to Sealab and marine life from shipping.
