Moon in Scorpio

Newly married couple Linda and Allen plan to take a trip to Acapulco for their honeymoon. Joining them on the cruise are Burt, the owner of the yacht, his wife, Claire, along with an additional couple Mark and his wife, Isabel. Burt and Mark are Vietnam War veterans and friends of Allen. Prior to the yacht leaving the harbor, a marina employee is stabbed to death by a mysterious figure in black pajamas.

The couples meet on the boat and set sail. During the voyage, wartime flashbacks show the three men committing atrocities during their tour of duty in Vietnam to include the murdering of innocent villagers. The men are clearly troubled by this and tensions on the ship, some of which are sexual, begin to rise. Soon, the boat is vandalized, rendering some of the navigation and communications equipment inoperable. Isabel begins acting erratically and mentions several times that when the “moon is in scorpio”, bad things happen. In a short period of time, Mark, Burt and Claire are gruesomely killed, leaving only Linda, Allen, and Isabel as the survivors. Allen is killed later; as Linda looks for him on the yacht, she surprises Isabel who is in possession of the murder weapon, an odd-shaped grappling hook.

Isabel tries to kill Linda and the two women fight each other. The fight ends when Linda overpowers Isabel and stabs her to death with the grappling hook. The entire story is told via flashbacks, from Linda's point of view, as she is the only survivor. The movie opens with an unseen person escaping from a mental institution and Linda in a hospital being comforted by a doctor. The movie closes with Linda being released from the hospital after she has narrated her story to the police.

In an on-line documentary, Graver explained the difficulties in making the picture for less than $250,000 and how those difficulties were exacerbated by a two week filming schedule. Graver, who died in 2006, also explained how the executive producer, Moshe Diamant, continually interfered with the project and significantly altered Robert Aiken’s screenplay. The original story line described how the veterans had burned down a Vietnamese temple dedicated to a “snake goddess” and that years later, a young Vietnamese child came to the United States to exact revenge on the soldiers. Diamant believed the story line was too confusing and instead demanded that Graver make a mad slasher movie, similar to Halloween but set on a yacht. The result, according to Graver, was some of both, but mostly confusion. Worse, Graver explained, after he went on vacation following the conclusion of the editing, Diamant hired another editor to re-arrange the scenes, creating yet more confusion. Graver claimed that Moon in Scorpio was the only project he ever worked on that made him want to “get into a fistfight.” Although the movie was never released theatrically, Graver claimed it made the producers more than a $1,500,000 profit from video sales and TV and cable showings.^[1]
