The Lost Continent (1968)

In 1968 the dilapidated freighter Corita hastily leaves Freetown to avoid a customs inspection. Captain Lansen (Eric Porter) has a cargo of dangerous explosives which he is smuggling so he can finally retire. His ship’s passengers also have reasons for leaving in a hurry. Dr. Webster (Nigel Stock), together with his daughter Unity (Suzanna leigh), is relocating due to his indiscretions with patients and illegal operations. Alcoholic pianist Harry Tyler (Tony Beckley) is aimlessly drifting from port to port. Eva Peters (Hildegard Knef) is fleeing from her husband with stolen bearer bonds which she intend to use to buy back her son from his evil clutches Caracas. Ricaldi (Ben Carruthers), a questionable lawyer, is pursuing Eva to retrieve the stolen bonds. First officer Hemmings (Neil McCallum) suggests that the ship should return to Freetown after an imminent Hurricane warning. The Captain asks the passengers and they are unanimous that they do not wish to return. However a mutinous crew, the bad weather and the instability of the explosives force everyone to abandon ship. The survivors find themselves adrift in a lifeboat surrounded by a strange carnivorous seaweed.
