Intensity is a 1997 American television psychological thriller film directed by Yves Simoneau, and starring John C. McGinley, Molly Parker, Piper Laurie, and Tori Paul. Based on the 1995 novel of the same name by Dean Koontz, it focuses on a young woman who accompanies her friend home for Thanksgiving, only to be met by a violent serial killer.
Chyna Shepherd accompanies her friend Laura Templeton to her family's house in rural Washington for Thanksgiving dinner. A serial killer named Edgler Vess invades the house and kills Laura and her family, as Chyna hides in the killer's RV. When Vess stops at a gas station, Chyna escapes and asks the two attendants to call the police. Before she has time to explain, Vess returns and torments the two workers before brutally killing them with a shotgun. Chyna then learns that he is holding a 14-year-old girl named Ariel hostage in his basement. She becomes determined to save Ariel and uses one of the shopkeepers' cars to follow Vess back to his home. On the road she runs into a woman named Miriam and asks her to call the police. Miriam believes Chyna is disturbed and moves on.
Miriam stops at the gas station and finds the shopkeepers' bodies, leading her to believe Chyna's story. She makes a hysterical phone call to the police, telling them that they "need to save Chyna and Ariel," which the police interpret as the ramblings of a lunatic. Upon trying to fall back to sleep, the policeman, Ethan Trevaine, remembers the name Ariel from a missing person's case and begins investigating. Meanwhile, Chyna's car runs out of gasoline, so she abandons it in the middle of the road, forcing Vess to stop. As Vess pushes the car down an embankment, Chyna enters his RV and hides, unknowingly leaving foot prints. Vess suspects another person has entered the RV, but feigns obliviousness. He then kills Miriam when she tries to run him off the road and save Chyna. When they arrive at his home, Chyna attempts to free Ariel from a fortified room but is attacked and subdued by Vess.
As a captive, Chyna speaks with Vess and has flashbacks to her traumatic childhood: as a little girl, she witnessed her disturbed, abusive mother and her boyfriend kill her neighbors. In turn, Vess reveals his obsession with the "intensity" of any particular experience and declares his intention to kill both her and Ariel, but offers Chyna a slightly more merciful death if she agrees to aid him in mentally torturing Ariel out of her catatonia. The two have further existential conversations regarding God and the nature of good and evil.
When Vess is late returning to work after the Thanksgiving holiday, he lies and tells his boss he had to make a last-minute trip to Portland and got home later than expected. He departs, leaving Chyna chained to the dining room table. She watches in horror as one of Vess's other captives escapes from a drain hatch in his backyard, only to be mauled to death by Vess's bloodthirsty German Shepherds. Chyna manages to free herself and seizes the opportunity to escape with Ariel. After dressing in Vess's dog-training gear and spraying ammonia in the eyes of his dogs, Chyna attempts to flee with Ariel in Vess's mobile home, but unwittingly triggers an alarm that causes him to return home early.
Before they can make their escape, an unmarked vehicle and a police car arrive. Although Chyna believes Vess to be in the unmarked vehicle driven by Trevaine, it is revealed that Vess is actually a Sheriff who emerges from the police car and opens fire on Trevaine, killing him before turning his attention to the mobile home. Chyna and Ariel manage to escape back to Vess's house, where Chyna ultimately gets the better of Vess. She sets him on fire, confines him in Ariel's old room, and watches as he burns to death.
In the aftermath, Chyna visits Ariel in a psychiatric hospital but is denied custody of her in a hearing; she is told that the young girl will require extensive therapy to recover from her trauma. As Chyna prepares to leave without her, Ariel, speaking for the first time, suddenly calls out to her the name "Badger", a character from a story Chyna had told her about to help bring her courage while escaping from Vess. The two embrace, and it is implied that Chyna's custody of Ariel was granted.
Intensity aired in two parts on Fox network on August 5 and August 6, 1997, respectively.[2] The film was the first summer-released miniseries or television film produced by Fox at the time.[3]
Ron Miller of Knight Ridder News praised the film as a "horror masterpiece, intelligently conceived and brilliantly executed, and the best program of its time television has ever produced."[4] Tom Shales of The Washington Post panned the film for its graphic subject matter, writing: "Intensity is certainly not without its shocks and scares. But the whole thing is so stomach-churning and nasty that you don't so much watch it as subject yourself to it. Life is really much too short to spend four hours of it with a preening, prancing monster like Edgler Vess."[5]
Hal Boedeker of The Baltimore Sun criticized the film for its plot holes and cliched elements, writing: "So it pushes the boundaries for made-for-TV thrillers. Do we need to start a national furor over it? Nope. Don't watch. A more crucial rating for Intensity would be a big fat I (for illogical)."[6]
Comparison of the relative warming in Hurricane Hilda (H; Hawkins and Rubsam 1968) and that derived from application of the thermodynamic model to the mean August sounding at Barbados (B). Data are normalized to the maximum temperature perturbation, light solid lines indicate the total warming in the eye, solid lines the warming at the eyewall (taken to be 1.5 RMW for Hilda), and dashed lines are the additional warming from the eyewall to the eye.
Scatterplots of the SST variation of MPI estimates from the indicated stations: (a) imposed upon the empirical curve for the North Atlantic derived by DeMaria and Kaplan (1994) and (b) new curves indicating the differences between developing cyclones and those that are decaying while moving over colder water.
A thermodynamic approach to estimating maximum potential intensity (MPI) of tropical cyclones is described and compared with observations and previous studies. The approach requires an atmospheric temperature sounding, SST, and surface pressure; includes the oceanic feedback of increasing moist entropy associated with falling surface pressure over a steady SST; and explicitly incorporates a cloudy eyewall and a clear eye. Energetically consistent, analytic solutions exist for all known atmospheric conditions. The method is straightforward to apply and is applicable to operational analyses and numerical model forecasts, including climate model simulations.
The derived MPI is highly sensitive to the surface relative humidity under the eyewall, to the height of the warm core, and to transient changes of ocean surface temperature. The role of the ocean is to initially contribute to the establishment of the ambient environment suitable for cyclone development, then to provide the additional energy required for development of an intense cyclone. The major limiting factor on cyclone intensity is the height and amplitude of the warm core that can develop; this is closely linked to the height to which eyewall clouds can reach, which is related to the level of moist entropy that can be achieved from ocean interactions under the eyewall. Moist ascent provides almost all the warming above 200 hPa throughout the cyclone core, including the eye, where warm temperatures are derived by inward advection and detrainment mixing from the eyewall. The clear eye contributes roughly half the total warming below 300 hPa and produces a less intense cyclone than could be achieved by purely saturated moist processes.
