SEA FEVER is a cross between mystery and horror similar to the ALIEN film franchise. The film is set in the sea where a bizarre creature hitches a ride on a departing trawler.
The assorted crew is comprised of a young female red-haired scientist Hermione Corfied), a couple who needs a big haul of fish to pay their debts (Dougray Scott and Connie Nielsen) and others waiting to be disposed off by the creature and its living microbes. It does not help that the crew believes that the red hair will bring bad luck on the trip. It is assumed that the boat leaves Ireland since most of the characters speak with an Irish accent.
The horrors come fast and furious aided by some effective and scary special effects. All works rather well except for the loose end that the creature is still in the waters after everything is over, ready and able to eradicate the human race when it attacks the next boat.
