Urban Legends: Final Cut

Amy Mayfield (Jennifer Morrison) is unsure about her thesis. But after a conversation with security guard Reese Wilson (Loretta Devine) about her experience with a series of murders that had happened on the campus she had previously worked in, she decides to make a film about a serial killer murdering in the fashion of urban legends.
Meanwhile, a student named Lisa (Jacinda Barrett) feels dazed and prepares to leave the bar, when someone abducts her. She wakes up in a bathtub filled with ice and discovers that her kidney was removed. Attacked by her abductor, she tries to flee through the window and is decapitated in the process. Lisa is not missed as she was about to go on a trip. The next day, Amy is preparing the shooting of her thesis film but is deserted by the assigned camera man, Toby Belcher (Anson Mount), who accuses Amy of stealing his thesis idea. Shooting begins with another camera man, Simon. When Sandra (Jessica Cauffiel), Amy's actress friend who played a victim in a scene, returns to an empty studio after forgetting her keys, she is attacked and slashed to death with a straight razor by the same killer who killed Lisa. Her friends witness her death when the material is smuggled into a sequence of takes of the scene, but discount it as another piece of acting, wondering who shot it. As there is no body and Sandra was about to go on a trip, her disappearance goes unnoticed.
Travis (Matthew Davis) is found to have committed suicide at the campus tower. At the funeral, Amy is offered help by Graham (Joey Lawrence), a student from a prosperous Hollywood background. She refuses, wishing to make it on her own. This offends Graham, who thinks it hypocritical, as Amy grew up in Hollywood as the daughter of a famous documentary film maker before moving to Chicago. After she has detected the assault on Simon on the tapes, she is confronted by the killer. During the ensuing chase, she loses the tapes and cannot prove her claims to a skeptical Reese. Amy now believes the claims of Trevor and meets up with him but, he still refuses to inform the police, hinting at a criminal past.
The next scene to be shot involves the "Tunnel of Terror", which is set up in an old carnival ride. Sophomores Stan (Anthony Anderson) and Dirk (Michael Bacall) are attacked and electrocuted by the killer while preparing the tunnel. Amy, who is taking a tour of the tunnel, discovers the corpses and is again confronted by the killer. She escapes again and informs the police, who attribute the deaths to accidental electrocution. Amy is comforted by Trevor. They begin having sex when Trevor suddenly stabs Amy. She wakes up and realizes that it was only a dream. Seeing a light on at the bell-tower, she decides to go there and finds her lesbian friend, Vanessa (Eva Mendes) waiting for her with a note. After a discussion, a mannequin falls on the table they run all the way to the top of the tower where Vanessa is captured. While trapped in the room, Amy encounters the corpses of Simon and Sandra and bashes the door down to find Vanessa's body hanging from a bell. Amy runs out of the tower, where Reese spots her; Amy meets up with Trevor, who tells her he has found that all the murder victims worked on Travis's thesis film.
After watching some of Travis's film, The Gods of Men, they suspect Toby, the only person who worked on the film who is still alive. They kidnap him and call in Professor Solomon (Hart Bochner) to present their suspicions. However, Toby reveals that Travis faked Toby's sound credit to help him graduate, admitting that he never went anywhere near Travis's film.
In the confusion, It is now revealed that the killer who murdered Amy's friends is none other than Solomon, who is taking revenge by killing everyone who managed to work with Travis so he can frame Amy in the process so he can go to L.A. with the award himself, Trevor manages to disarm the professor. Solomon then threatens Trevor with a shovel while Amy gets hold of the gun and threatens Solomon. Reese then shows up and, at her command, Amy drops the gun and kicks it away. There is a commotion and several racks are knocked over, scattering prop guns all over. Amy gets hold of Reese's gun and holds it on Solomon, but hesitates to fire. Solomon attacks her again, but she shoots him unconscious. The scene then cuts to the Hitchcock awards, where an award is posthumously given to Travis. As Trevor is about to accept the award on his late brother's behalf, a sniper appears in the rafters, only to be shot down by Reese. The altercation is then revealed to be a scene in Amy's new film, Urban Legends. It's also revealed that Toby and Graham survived their attacks and are now busily working on her behalf.
The final scene shows Solomon in a mental institution where, after watching Amy's film, a nurse asks him if he enjoyed the movie. He is wheeled out by the nurse, Brenda Bates (Rebecca Gayheart), who tells him that they have a lot in common.
