Spielberg's screenplay divides Close Encounters roughly into three acts, basically corresponding to each of the three kinds of "encounters."

In the first category, sightings of a UFO, we first see a very strange sight in the Mexican desert: an international team of researchers led by French UFO expert Lacombe (the late Francois Truffaut) and guided by several Mexican Federales finds five World War II vintage Grumman TBM Avengers. The planes are abandoned but strangely intact, as though they were brand new. "Who flies this kind of plane?" asks a bewildered cartographer/interpreter named Laughlin (Bob Balaban).

"No one," replies another astonished researcher. "This is Flight 19."

(Flight 19, of course, is a reference to a Navy training flight which took off from Ft. Lauderdale one morning in December 1945 and vanished, along with a Martin Mariner search plane sent up to look for the missing planes and crews. Flight 19 is now famous in the lore of unsolved mysteries related to the Bermuda triangle.)

Laughlin is baffled by something else, as well. A Mexican villager, old, sunburned, and seemingly delirious, keeps repeating, "El sol salio anoche y me canto. El sol salio anoche y me canto." When Laughlin asks what the phrase mean, a researcher who is fluent in Spanish says, in an awed tone, "He says the sun came out last night. He says it sang to him."

Later, in the Indianapolis Air Traffic Control Center, a more dramatic close encounter of the first kind plays out on the radar scopes as airliner pilots call in reports of bright lights in the sky and unknown contacts make their presence known. For a few tense minutes it look as though tragedy is imminent, but within moments the contacts vanish into the night sky. Torn between reporting a UFO sighting or just letting the incident slide by, pilots and air traffic controllers alike opt to keep quiet, mainly to avoid having to fill out tons of bureaucratic paperwork.

As important as these sequences are, the focus of Spielberg's story is on Roy Neary (Richard Dreyfuss), an employee of a Midwestern power company whose life on Earth is ordinary, hectic, and somewhat unfulfilling. Sent out to investigate a section of power lines in rural Indiana (caused, of course, by the UFOs' passage), Neary has a close encounter of the first kind and impulsively goes on a truck-borne pursuit of two small "flying saucers." This sequence, which ends with a Keystone Kops-like police chase of the same UFOs, triggers an obsession within Neary that neither his wife Ronnie (Teri Garr) nor his children will understand, much less accept. Neary, along with several hundred other people from different towns and states, will soon be haunted by both a visual image and a simple five-note musical phrase. The traces of the UFO flights that leave traces behind (sunburn on people who, like Neary, were exposed to bright light at night) are known as close encounters of the second kind.

Spielberg weaves Neary's everyman-faces-an-extraordinary- situation plot with the official investigations being carried out by the UN-sponsored Lacombe team and a more secretive U.S. government First Contact program. These plot threads will all lead to a climactic and awe-inspiring close encounter of the third kind: actual (and documented) contact between humanity and another space-faring civilization.

The Columbia/Tri-Star Collector's Edition brings not only a newly re-edited version (trimming some excess material from the 1980 Special Edition) of the 1977 film, but also comes with a second disc loaded with extras such as a Laurent Bouzereau documentary on the making of Close Encounters of the Third Kind, a 1977 promotional featurette, and the theatrical trailers.
