Wild Things: Diamonds in the Rough

Marie Clifton is set to inherit two beautiful diamonds, called the "mother and daughter", which her late mother bestowed to her. Marie's stepfather, Jay Clifton, challenges the will, claiming Marie is not ready for the responsibility, but actually just wants to take the diamonds for himself. At a sexual education seminar at Marie's school, physician Dr. Chad Johnson and probation officer Kristen Richards discuss sex crimes, and Richards reveals she was a victim of an anonymous rapist many years before.

At Marie's swim-meet, Jay encounters towel girl Elena Sandoval, and invites her to Marie's eighteenth birthday party. Elena attends the party but is assaulted by Marie, who says that Elena is not welcome. Jay comforts Elena and brings her to the construction site of one of his buildings for privacy. Later, Elena alleges that Jay raped her at the site. Detective Michael Morrison is placed on the case, as is Richards, who is Elena's probation officer. Chad is placed in charge of documenting Elena's injuries, and testifies to the court that Elena was raped.

Marie believes that Elena is doing this for money and tells Jay to pay her off. When Jay admits he is broke, Marie suggests that they sell the diamonds. Jay agrees and revokes his claim to the will, giving Marie custody of the diamonds so she can sell them off. However, this was a ploy between Elena, Marie, and Chad to get the diamonds, and the trio are in a sexual relationship together.

Jay believes that Elena will recant her accusation after being paid off, but at the next court session she testifies that he also threatened to kill her. Jay is sent to prison, but Richards is now suspicious of Elena's behavior. Richards and Morrison search Elena's trailer and discover she has gathered information about Kristen's rape, using it to form her testimony. Richards and Morrison discuss their suspicions with Jay and conclude that Marie, Elena, and Chad must be working together.

Chad is questioned by Richards and Morrison, and fears they suspect him. He turns on Marie, drugging her and stealing the diamonds. Marie and Elena chase Chad into the woods, where Marie kills him with a tire iron. She then meets the diamond buyer Chad set up, but learns that the diamonds are fake. Elena, who is left to deal with Chad's body, is caught by Richards and Morrison.

Richards and Morrison give Elena a task: wear a wire and get Marie to admit she killed Chad, and the charges against Elena will be lessened. Elena goes to Marie and plays along with her plan to get the real diamonds from Jay's safe at the construction site. Throughout, Elena repeatedly tries to get Marie to confess, but to no avail. When they finally open the safe, Elena pulls a gun on Marie and flees with the diamonds, prompting Marie to chase her with her own gun. Richards and Morrison, who are listening in from nearby, enter the construction site separately. During the hide-and-seek, Richards finds Marie and shoots her dead. Afterward, Elena claims there were no diamonds, and Richards escorts her from the scene.

At the end, it is revealed that Richards and Elena are mother and daughter; Jay was the man that raped Kristen in the past, and Elena is their daughter. They dispose of him by dosing his drink and leaving him to fall to his death. During the credits, scenes are shown explaining how they managed to pull their plan off.
