Julie Richman, portrayed by Deborah Foreman, is an archetypal "Valley girl" navigating life in the vibrant San Fernando Valley, Los Angeles. She appears to have it all – striking looks, a close-knit circle of popular friends, and a charming boyfriend named Tommy, played by Michael Bowen. Yet, beneath the surface, Julie begins to question her relationship with the arrogant and self-absorbed Tommy.
After a day of shopping with her pals—Loryn, played by Elizabeth Daily, Stacey, depicted by Heidi Holicker, and Suzi Brent, characterized by Michelle Meyrink—Julie encounters Tommy and decides to end their relationship. Later at the beach, she shares meaningful looks with a mysterious young man in the distance.
The following night, at Suzi's party, Julie’s life takes an unexpected turn when she meets Randy, a Hollywood punk played by Nicolas Cage, who has crashed the gathering alongside his friend, Fred, performed by Cameron Dye. Their instant connection deepens as Julie realizes Randy is the same guy from the beach. Meanwhile, Tommy, consumed by jealousy, makes a futile attempt to lure Loryn into bed and subsequently orchestrates the ejection of Randy and Fred from the party.
Undeterred, Randy cleverly sneaks back into the party, hiding out in an upstairs bathroom shower, waiting for Julie to enter. Amid the noise of partygoers engaging in various activities, Randy persuades Julie to escape the chaos with him. She ends up bringing a hesitant Stacey along for the exhilarating ride to Randy’s favorite Hollywood nightclub. As tensions rise with Stacey turning down Fred's advances, Julie and Randy's bond solidifies, setting the stage for a thrilling romance.
However, Julie's friends express their disapproval of her relationship with Randy, pushing her to reunite with Tommy. Seeking guidance, Julie approaches her father, played by Frederic Forrest, who encourages her to pursue her feelings. Ultimately, she chooses to reconcile with Tommy, breaking Randy’s heart in the process. Devastated, Randy drowns his sorrows in alcohol, kisses his ex-girlfriend Samantha, portrayed by Tina Theberge, and narrowly escapes a confrontation with a gang, thanks to Fred’s timely intervention.
Fred advises Randy to fight for Julie, prompting a whirlwind of fervent moments as Randy seeks glimpses of her throughout the Valley. Fred hatches a plan to win Julie back and take revenge on Tommy, setting into motion a series of events that will explosively unfold.
A secondary storyline follows Suzi and her stepmother Beth, showcased by Lee Purcell, as they vie for the attention of a boy named Skip. Suzi eagerly anticipates his arrival at the party, but complications arise when Beth and Skip’s mutual attraction is revealed.
As prom night approaches, Julie learns that Tommy has planned a special evening for her at the Valley Sheraton Hotel. They arrive in a lavish stretch limousine, while Randy and Fred sneak backstage at the prom. Growing increasingly frustrated by just watching the festivities, Randy finally confronts Tommy when they are announced as king and queen. An explosive fight breaks out between the two, culminating in Randy triumphantly escorting a delighted Julie away from the chaos.
As they escape in the limelight of Tommy’s rented limo, Julie symbolically discards his I.D. bracelet, a keepsake of their relationship, into the night. In a poignant nod to classic cinema, the scene pans out over the illuminated Valley skyline, reminiscent of the iconic ending of The Graduate, as the couple rides into their uncertain future.
