The Fear-Makers

After Seaview's sister ship, Polidor, is lost on an experimental deep dive, Seaview continues with the tests. Unknown to the already stressed crew, one of the visiting psychologists aboard is an enemy agent who has released a fear-causing gas into the air system. As Seaview plunges into the depths a dangerous panic starts to spread.

El Polidor, un submarino atómico diseñado, como el Seaview, por el Almirante Nelson, naufraga en su primer viaje y todos sus tripulantes mueren .¿Accidente o sabotaje? Nelson sostiene la segunda hipótesis, mientras que, en el interior de su submarino, se propaga un extraño gas que produce un terror incontrolable en quien lo respira.
