Final Examination
A police officer fails in capturing a drug dealer in Los Angeles, so his boss Hugh Janus transfers him to Hawaii for disciplinary reasons. On the island some former female students are just gathering in a luxury hotel. The young ladies once belonged to the sorority "Omeaga Kappa Omega" and are now invited to an erotic photo shoot which is organised by Derek Simmons, the editor of the Cavalier Magazine. Shortly after their arrival, Terri Walker, one of the former students, is strangled in the pool while her friend William Culp is absent for some minutes. Detective Newman begins to investigate the murder together with his new colleague Julie Seska and the coroner Ferguson. Next to Terri's corpse they find a document which resembles a final examination certificate and has the imprint "Failed" on it. William tells them to observe Derek Simmons very closely.
In the following night, the next student dies. Amanda Calvin is lured outside to the pool by a phone call and falls victim to the unknown murderer. Later the cops find William in the hotel room of the student Megan Davidson, who also belongs to the group. They just had sex and now they are questioned. The cops get to know the background of the series of murders. Five years ago, Rachel Kincaid committed suicide by falling from a bridge in her car. At that time she was the favourite for the election of the sorority's speaker, but she was mobbed by her competitor Kristen Neal, who is also present in Hawaii now.
After Newman and Seska have clarified these connections, William wants to inform them about something. But before Newman meets him, the young man is killed by the murderer and can only indicate that there is some problem with Rachel. Newman again gets in contact with his colleague Rita in Los Angeles, who had already provided him with the file about Rachel, and asks for Simmons. Rita gets to know that the editor of the magazine is actually called James Derek Kincaid and that he is Rachel's brother. He has gathered the students in the hotel to take revenge for his sister's death.
Megan and Kristen, who are the only surviving people among the invited students, meet at the hotel room. It is the fifth anniversary of Rachel's suicide. Kristen suspects Megan and threatens her with a pistol. Suddenly the lights go out and she forces Megan to go into the hallway where she runs across the murderer. Kristen is able to expel the killer, but accidentally shoots at Seska. Newman just arrives in time to stop the killer who really proves to be Simmons alias Kincaid.
With the help of a photo, the detective realises that the case is not yet complete. As he has been intimate with the photographer Tayler Cameron before he recognizes her necklace. She is a sister of Rachel and Derek. Now she overwhelms Kristen and threatens to strangle her. When Newman intervenes, she escapes to a rock over the pool. She stabs a knife in her body and falls down into the water. The cop just wants to announce the next corpse, but she attacks him. Newman shoots Taylor in self-defense.
At the same time his colleagues in Los Angeles arrest professor Andrews, who was not only Rachel's study adviser, but also impregnated his student before she died. When they arrive at the police station, the cop Sam reveals to be another brother of Rachel. He shoots the professor.
