Oxygen (film)

Oxygen is a 1999 film, directed and written by Richard Shepard. The film follows a troubled cop, Madeline Foster (played by Maura Tierney) as she pursues a kidnapper who calls himself Harry Houdini (Adrien Brody). The film was shot on location in New York City.

Plot

"Harry Houdini" (Adrien Brody) has kidnapped and buried alive a rich businessman's wife. He demands $1 million in cash from the woman's husband in return for the release of the location of her burial site before she runs out of oxygen. He also states that if police involvement is initiated, he will ensure she is never found alive. As expected, however, police involvement is initiated and Detective Madeline Foster (Maura Tierney) is assigned with the task of finding the buried woman and catching Houdini.

It is quickly realized though that Houdini, in fact, wanted the police to get involved so he could commit a second kidnapping - that of Foster. When Houdini is finally caught as the result of a car chase involving him and Detective Foster, she attempts to get him to reveal the location of his buried victim. When Foster's initial interrogation of Houdini proves unsuccessful, the FBI are assigned to take over the case, although they do not have any more luck. In a plot twist, it is revealed that Houdini has already committed a murder, that of his accomplice. He now has nothing to lose and the police realize the death of the buried woman would not be as significant as first thought.

Oxygen

Oxygen is a chemical element with symbol O and atomic number 8. It is a member of the chalcogen group on the periodic table and is a highly reactive nonmetal and oxidizing agent that readily forms compounds (notably oxides) with most elements. By mass, oxygen is the third-most abundant element in the universe, after hydrogen and helium. At standard temperature and pressure, two atoms of the element bind to form dioxygen, a colorless and odorless diatomic gas with the formula O
2. Diatomic oxygen gas constitutes 20.8% of the Earth's atmosphere. However, monitoring of atmospheric oxygen levels show a global downward trend, because of fossil-fuel burning. Oxygen is the most abundant element by mass in the Earth's crust as part of oxide compounds such as silicon dioxide, making up almost half of the crust's mass.

Many major classes of organic molecules in living organisms, such as proteins, nucleic acids, carbohydrates, and fats, contain oxygen, as do the major inorganic compounds that are constituents of animal shells, teeth, and bone. Most of the mass of living organisms is oxygen as it is a part of water, the major constituent of lifeforms. Oxygen is used in cellular respiration and released by photosynthesis, which uses the energy of sunlight to produce oxygen from water. It is too chemically reactive to remain a free element in air without being continuously replenished by the photosynthetic action of living organisms. Another form (allotrope) of oxygen, ozone (O
3), strongly absorbs UVB radiation and consequently the high-altitude ozone layer helps protect the biosphere from ultraviolet radiation, but is a pollutant near the surface where it is a by-product of smog. At even higher low earth orbit altitudes, sufficient atomic oxygen is present to cause erosion for spacecraft.
