Given the question: Build a movie plot around this: Whose dead body is locked in a cabin to use as evidence? I think part of the plot synopsis is missing.
The answer is:
A man fires a bullet into the head of a body wrapped in a sheet. He says to an off screen person, "The boat can leave now. Tell the crew."Several days later, an apparently abandoned sailboat sails into New York harbor. Two officers of the harbor patrol board the boat to investigate and find the living quarters in squalor and disarray. They are suddenly attacked by a rotting, bloated zombie (Captain Haggerty) which bursts from the hold, gorily killing one officer by biting his throat out, before being shot and propelled overboard by the second officer.A local reporter named Peter West (Ian McCulloch) is assigned by his hard-nosed editor (director Lucio Fulci) to the case. That evening he meets up with Anne Bowles (Tisa Farrow) the daughter of the boat's missing owner. Anne has informed the police that she has not seen her father for the past three months since he traveled to the Antilles. Meanwhile at the morgue, the pathologist and his assistant are preparing to perform an autopsy on the dead police officer, when unknown to them, the dead body begins stirring...The next morning, Peter and Anne fly to the Dominican Republic and meet an American tourist couple named Brian Hull (Al Cliver) and Susan Barrett (Auretta Gay) who are about to embark on a sailing tour of the Caribbean. Peter and Anne ask them to help them get to the island of Matul, where Anne's father was last heard from. Despite Brian's claim about warnings from the superstitious locals about Matul, the four of them agree to set off together for the island.On Matul, tensions between Dr. David Menard (Richard Johnson) and his contemptuous, highly strung-out wife Paola (Olga Karlatos) are running high. She wants to leave island, terrified about reports of zombie attacks. He insists on staying to conduct research into the phenomenon, despite the fact that his medical mission is falling apart. Leaving her alone to drink her fears away at their isolated beach house, Menard drives in his jeep to his hospital, which is a ramshackle converted church buzzing...
