===Season 1===
[[File:Sheryl Lee.jpg|alt=|thumb|upright|Season one of ''Twin Peaks'' focuses on the mystery of who killed Laura Palmer, played by [[Sheryl Lee]], pictured in 1990.]]
In 1989, local logger [[Pete Martell]] discovers a naked corpse wrapped in plastic on the bank of a river outside the town of [[Twin Peaks, Washington]]. When [[Harry S. Truman (Twin Peaks)|Sheriff Harry S. Truman]], his deputies, and doctor [[List of Twin Peaks characters#Will Hayward|Will Hayward]] arrive, the body is identified as high school senior and [[homecoming queen]] [[Laura Palmer]]. A second girl, [[Ronette Pulaski]], is discovered as well, who is badly injured and [[fugue state|dissociative]] just across the state border.

FBI Special Agent [[Dale Cooper]] is called in to investigate. Cooper's initial examination of Laura's body reveals a tiny typed letter "R" inserted under her fingernail. At a town conference, Cooper informs the community that Laura's death matches the signature of a killer who murdered another girl in southwestern Washington the previous year, and that the evidence potentially indicates the killer being from Twin Peaks.

Through Laura's diaries, local law enforcement alongside Agent Cooper discover that she had been living a [[double life]]. She was cheating on her boyfriend, football captain [[Bobby Briggs]], with biker [[James Hurley (Twin Peaks)|James Hurley]], and prostituting herself with the help of truck driver [[Leo Johnson (Twin Peaks)|Leo Johnson]] and drug dealer [[Jacques Renault]]. Laura was also addicted to cocaine, which she obtained through coercing Bobby into doing business with Jacques.

Laura's father, attorney [[Leland Palmer]], suffers a [[nervous breakdown]] after her death. Her best friend [[Donna Hayward]] begins a relationship with James. With the help of Laura's cousin [[Maddy Ferguson]], Donna and James discover that Laura's psychiatrist, [[Dr. Lawrence Jacoby]], was obsessed with her, but he is proven innocent of the murder.

Hotelier [[Ben Horne]], the wealthiest man in Twin Peaks, plans to destroy the town's lumber mill along with its owner, [[Josie Packard]], and murder his lover, Josie's sister-in-law and Pete's wife [[Catherine Martell]], so he can purchase the land at a reduced price and complete a development project called Ghostwood. Horne's sultry, troubled daughter, [[Audrey Horne|Audrey]], becomes infatuated with Agent Cooper and spies on her father for clues in an effort to win Agent Cooper's affection.

Cooper has a dream in which he is approached by a one-armed otherworldly being who calls himself [[Mike (Twin Peaks)|MIKE]]. MIKE says that Laura's murderer is a similar entity, [[Killer BOB]], a feral, denim-clad man with long gray hair. Cooper finds himself decades older with Laura and [[The Man from Another Place|a dwarf in a red business suit]], who engages in coded dialogue with Cooper. The next morning, Cooper tells Truman that if they can decipher the dream, they can find out who murdered Laura.

Cooper and the sheriff's department find the one-armed man from Cooper's dream, a traveling shoe salesman named Phillip Gerard. Gerard knows a Bob, the veterinarian who treats Renault's pet bird. Cooper interprets these events to mean that Renault is the murderer, and with Truman's help, tracks Renault to One-Eyed Jack's, a brothel owned by Horne across the border in Canada. He lures Renault back onto U.S. soil to arrest him, but Renault is shot while trying to escape and is hospitalized.

Leland, learning that Renault has been arrested, sneaks into the hospital and smothers him to death. The same night, Horne orders Leo to burn down the lumber mill with Catherine trapped inside and has Leo gunned down by [[Hank Jennings]] to ensure Leo's silence. Cooper returns to his room following Renault's arrest and is shot by a masked gunman.
