One Tree Hill

Nathan challenges Lucas to a nighttime one-on-one basketball game. If Nathan wins, Lucas must not join the team; if Lucas wins, Nathan will quit.

After failing in his first varsity basketball game, Lucas decides to quit the team. Meanwhile, Nathan and Peyton's faltering relationship continues to weaken as Peyton tires of Nathan's poor treatment of Lucas. And Keith forces Karen to deal with her resentment towards Dan after she refuses to attend Lucas' games.

After a particularly spectacular basketball game, Lucas quickly supplants Nathan as the team's most popular player. Frustrated by Lucas' success, Nathan rallies his teammates and begins a hazing campaign against Lucas. Meanwhile, Peyton becomes upset with Lucas because he submitted her drawings to a hip magazine without her knowledge. Also, Karen confronts her rival from high school.

Haley convinces Lucas to go with the team to a party at Nathan's beach house, hoping that the guys will become friendlier. When Lucas sees the wealth that is denied him, he finally confronts his mother about why she lets Dan ignore them. Meanwhile, when Nathan's mother, Deb Scott (BARBARA ALYN WOODS), returns home and tries to deal with her angry son, she turns to Karen for advice.

Lucas asks Keith to play with him in the annual "Father and Son" basketball game and realizes he got the better father figure after Dan publicly humiliates Nathan on the court. Meanwhile, Peyton has a hard time dealing with the anniversary of her mother's death and finds a comforting ally in Whitey.

When Whitey ejects Lucas and Nathan from the team bus due to their misconduct on the basketball court, the half brothers are stranded 30 miles from home. Injured during the game, Brooke needs Peyton to drive her home. Meanwhile, Karen and Keith attend a business function, and tempers flare when Nathan's mother, Deb (BARBARA ALYN WOODS), is seated at their table with Dan.

The night of Dan and Deb's (recurring guest star BARBARA ALYN WOODS) annual basketball appreciation party spurs old memories and new feelings. Karen makes a new friend, Keith confronts Dan again, and Lucas finally makes his romantic intentions clear to Peyton. Meanwhile, Haley and Nathan grow closer until Brooke spreads a vicious rumor that devastates Haley.

Hoping to have fun, Brooke and Peyton attend a college party, but the situation gets bad when one of the guys, Gabe (MIKE ERWIN - "Everwood"), drugs Peyton. After Brooke calls Lucas for help, the friends bond while caring for the sleeping Peyton, prompting Lucas to gain a new appreciation for Brooke. Meanwhile, Haley gives Nathan another chance, and the two go on their first date.

After fighting with his father and Haley, Nathan succumbs to the pressure and takes amphetamines to help him play basketball better. However, he isn't prepared for the destruction the drugs do to both his body and his family. Meanwhile, Peyton intends to rekindle her relationship with Lucas, but when she arrives at his house, she witnesses him with Brooke.

Lucas and Peyton try to redefine their friendship after Lucas chooses to be with her best friend, Brooke, who is unaware that Lucas and Peyton briefly dated. Dan invites Deb (BARBARA ALYN WOODS) to a getaway, but she suggests he devote the time to Nathan. However, Dan and Nathan's father/son weekend ends abruptly. Lucas asks Nathan to join his team in a late-night basketball game.

Unable to cope with the pressure from Dan, Nathan quits the basketball team. Although Haley fears that Nathan will not need her emotional support as much now, he relies even more heavily on her. Meanwhile, Brooke becomes increasingly jealous of Lucas and Peyton's growing friendship.

After Peyton receives the devastating news that her father is lost at sea, she and Lucas take an overnight trip to Hilton Head, South Carolina, to identify a body that has washed ashore. Overcome with emotion, Peyton kisses Lucas. Meanwhile, an unexpected visit from Dan's parents leaves the Scott family in turmoil as numerous family secrets are revealed during Dan's birthday dinner.

On their way to drive Karen home from the airport, Keith and Lucas collide with an oncoming vehicle, leaving Lucas unconscious and fighting for his life. At that moment, Dan is traveling to Deb's house and he witnesses the accident. At the hospital, Dan must acknowledge that Lucas is his son in order to authorize emergency surgery. Meanwhile, Peyton decides to tell Brooke that she kissed Lucas.

While holding a vigil at Lucas' bedside as he lays in a coma, Karen meets Brooke, who is now dating Lucas, and learns from Deb (BARBARA ALYN WOODS) that Deb and Dan are getting divorced. Most shocking of all, Karen is horrified to discover that Keith was drinking alcohol while driving at the time of the accident. Meanwhile, Nathan tries to win Haley back after she breaks up with him.

After his near-death experience, Lucas decides he made the wrong choice in girlfriends. He breaks up with Brooke and secretly rekindles his romance with Peyton. However, the truth is revealed after he is rushed to the emergency room again, and the girls come face to face in the hospital. Meanwhile, Keith is unable to pay his mortgage because he had to cover Lucas' hospital bill.

Nathan must choose which parent to live with after Dan and Deb's divorce. Dan forces Nathan to make the decision by threatening to reveal Deb's (BARBARA ALYN WOODS) darkest secrets in court unless Nathan chooses him. Meanwhile, Lucas meets a beautiful stranger who challenges his perceptions of life since Lucas' car accident.

The gang hits the road to Charlotte, North Carolina, for a basketball game and an annual cheerleading competition that Brooke is determined to win. When one of the teammates gets sick, Brooke's fellow cheerleader Peyton begs Haley to join the squad for the competition. Meanwhile, after Whitey assigns Lucas and Nathan to the same hotel room, tempers flare, and Haley is caught in the middle.

Lucas, Nathan, their teammate Jake (recurring guest star BRYAN GREENBERG) and the rest of the Raven basketball players are auctioned to the highest bidder in the annual "Boy Toy" charity auction, and the evening leads to surprising developments. Meanwhile, having missed out on the auction, Brooke ends up with offbeat Mouth (recurring guest star LEE NORRIS) and gives him the night of his life.

Lucas must make a difficult decision regarding Brooke. Haley considers having sex with Nathan. Keith wants more from his relationship with Karen. And Dan tries to get runaway Nathan to return home.

While Nathan looks for an after-school job to pay his rent, Haley hosts a party at his apartment--but she panics when the situation gets out of control. After jilted Brooke realizes she was not invited to the festivities, she decides to attend the party anyway, along with her new friend, Nicki (recurring guest star EMMANUELLE VAUGIER - "Smallville").

Lucas is shocked to learn that Dan once asked Karen for joint custody of him when he was a baby. Meanwhile, Peyton panics after her friend Nicki (recurring guest star EMMANUELLE VAUGIER) kidnaps basketball player Jake's (recurring guest star BRYAN GREENBERG) baby while baby-sitting.

Lucas and Nathan bear the brunt of Dan's abuse as he coaches them into the playoffs, pushing both of them to their emotional breaking points. Haley is stunned after Dan threatens her, causing her to reconsider her relationship with Nathan. Meanwhile, Whitey finds out that his medical condition may be more serious than he first expected, and Dan learns a shocking secret from Deb.
