In the seventh season premiere, Nathan (series star James Lafferty) learns of a shocking accusation that could threaten his career, much to the chagrin of his sports agent, Clay (series star Robert Buckley). Brooke (series star Sophia Bush) prepares to launch a new fashion line, and Julian (series star Austin Nichols) decides to produce a big movie. Haley's (series star Bethany Joy Galeotti) sister, Quinn (series star Shantel Vansanten), makes a surprise visit. Meanwhile, Jamie (series star Jackson Brundage) celebrates his 7th birthday. Paul Johansson, Lee Norris, Antwon Tanner and Lisa Goldstein also star.

In an episode dedicated to the memory of the late writer/director John Hughes, chaos surrounds an '80s-themed alumni dance at the high school — Haley's birthday is forgotten, Jamie is left home alone and Nathan and Clay are stranded 200 miles from Tree Hill. Meanwhile, Brooke's appearance at the dance with Alexander (recurring guest star MITCH RYAN) forces Julian to relive his dorky adolescence.

Nathan tries to keep Haley calm after Taylor (guest star LINDSEY McKEON - Supernatural, Veronica Mars, IQ-145) shows up at their house with Quinn's ex-husband, David (recurring guest star SCOTT HOLROYD), in tow. Clay gets a chance to prove his commitment to Quinn by helping her through a dinner with David and Haley. Meanwhile, Julian sticks up for Alex (recurring guest star JANA KRAMER) on the set of their movie, and Brooke leans on Alexander (recurring guest star MITCH RYAN - upcoming The Pacific) to ease her heartache.

As Haley prepares to emcee the annual Tree Hill Burning Boat Festival, Brooke uses the opportunity to process her father's betrayal, while Julian tries to breathe new life into a past idea. Mouth and Millie make a change to their morning show, and Clay and Quinn get ready for Logan's (recurring guest star PIERCE GAGNON) first night at the beach house.

When a woman is found dead and her hair is done up '70s style complete with vintage clothes, the CSI team discovers clues that point to a killer with a hair fetish. (TV-14)
