Storyline: Seymour is a young man who works in a flower store. He manages to create a carnivorous plant that feeds on human flesh. Nobody knows about it, so Seymour and the plant become good 'friends'. The plant needs food to grow up, so it convinces him to start killing people.

Storyline: In the midst of World War II, the battle below the seas rages. The Nazi's have the upper edge as the Allies are unable to crack their war codes. That is, until a wrecked U-boat sends out an SOS signal, and the Allies realise this is their chance to seize the 'enigma coding machine'. But masquerading as Nazi's and taking over the U-boat is the smallest of their problems. The action really begins when they get stranded on the U-boat.
