U-4000 - Panik unter dem Ozean

When a volcano erupts, a deep-sea vessel full of scientists suffers damage and begins to lose control. To their rescue comes Captain MacKenzie (Joseph Cotton), commander of Alpha, a high-tech atomic submarine. The captain takes the crew to a secret underwater utopia called "Latitude Zero" that is dedicated to the preservation and protection of mankind. With a completely opposite agenda, the evil Dr. Malic (Cesar Romero) wishes to kidnap and experiment on the scientists in order to add to his roster of super-intelligent freak minions. Now it's up to Captain MacKenzie and his crew to save the day. (Verleiher-Text)
