Synopsis:
The Sea Devils are chosen to undertake an experiment in which they will live underwater in a domed house. The effects of living beneath the sea begin to manifest making the team irritable and irrational. Each begins hallucinating large monsters which attack the dome. They are also cut off from surface help by a large storm. Finally the hallucinated creatures are dispatched with a desperate surge of brain power from Dane. The team is then returned to the surface where they return to normal.
