Attracting approximately 7.4 million viewers, the episode became basic cable's most watched première since The Dead Zone. "Pilot" introduces the show's premise of 4400 people being abducted in the past, beginning from 1946, and all being returned to the present day in a flash of light at Highland Beach.

A comet suddenly changes trajectory and is heading towards Earth, apparently coming in for a "landing", 4400 people assumed dead or missing reappear. When 4400s begin to exhibit "abilities" Tom Baldwin and Diana Skouris are partnered to investigate them.

Plot

The episode begins on March 3, 1946. A young girl, Maia Rutledge (Conchita Campbell) of Crescent City, California, is with her parents in their car. Although it is raining outside, she persuades her parents to let her play nearby. While she is collecting flowers in the bushes, a light shines down on Maia, and she disappears. The next scene takes place on May 11, 1951 in South Korea. A young black soldier, Richard Tyler (Mahershalalhashbaz Ali), is being beaten by his fellow officers. One of them remarks, "We treated you like an equal, but that wasn't good enough for you. You had to cross the line." A fellow soldier then drops a photo booth strip on the floor; the pictures are of Richard with a young white woman. Moments later, the same light which abducted Maia shines on Richard, and he vanishes.

In 1979, Orson Bailey (Michael Moriarty), a partner at an insurance firm, is preparing to leave his office to take his wife on a date. As he approaches his car, the light appears and he vanishes as well. Next, teenage cousins Shawn Farrell (Patrick Flueger) and Kyle Baldwin (Chad Faust) are on a beach at night in the year 2001, drinking beers and talking about their personal lives. The light shines on them, and Kyle drops to the ground, alone and unconscious. The episode jumps to the present day with Kyle in a hospital bed, hooked up to a respirator. His father, Tom Baldwin (Joel Gretsch), is comforting him.

Elsewhere, Diana Skouris (Jacqueline McKenzie) receives a call on her cell from Dennis Ryland (Peter Coyote) telling her to "Get over here, now!" As Diana arrives at NTAC, Ryland announces that the country is at DEFCON One. Diana asks to be brought up to speed, and an unnamed co-worker tells her that the comet is no longer a fly-by; it is heading toward the earth. Countries around the world begin deploying missiles in an attempt to destroy the comet.

As it enters the atmosphere of Earth, Diana remarks that the comet is slowing down, "as if it's coming in for a landing." As she tells Ryland the co-ordinates of where the comet's trajectory will land it, Dennis states that it is near Mount Rainier, their "back yard." Arriving at the landing spot of the comet, a multitude of cameramen and reporters have set up. Diana looks on as the comet slowly comes in to land, hovering over a lake and causing ripples to form in the water. While emitting a sound, the comet begins to shrivel and lose its cohesion. Seconds later, the ball of light explodes, sending a shock-wave that knocks over the onlookers. Returning to their feet, they discover the comet is gone, and thousands of people have appeared.

Back at NTAC, Tom and Dennis argue in Dennis' office. Tom tells him he needs answers, and that he will come through for Dennis. After this Dennis introduces Tom to Diana, explaining how, together, they will make a good team investigating the return of the 4400.

The 4400 are quarantined at a Homeland Security facility where they are questioned. Tom meets with Shawn and questions him, expressing frustration when Shawn indicates that he does not remember anything. Orson becomes angry when inquiring about his release, causing a nose bleed. Richard meets Lily (Laura Allen), and finds out that she is the granddaughter of his former girlfriend, who has since died.

The ACLU successfully sues for the release of the 4400. Homeland Security provides them with temporary living expenses, and many are reunited with family.
