Welcome to Laguna Beach and the life of eight high school friends who were born and raised in this beautiful seaside town. As the senior girls prepare for one of their infamous hotel parties, Stephen is torn by his attraction to two girls, Kristin and LC. After Kristin confronts him about his night with LC, sparks fly as they all attend the Black & White party.
A double-date dinner turns from bad to worse when Stephen gets jealous about phone calls Kristin is receiving from another guy. LC and Lo drop in on Trey's AYA (Active Young America) Open Mic Night, and the whole gang gathers for a bonfire on the beach where things heat up between LC, Stephen and Kristin.
When LC, Stephen and Trey check out a designer fashion show in LA, LC watches Stephen's attention turn from fashion to fashion models. Meanwhile in Laguna, Kristin, Alex, and Sam, a junior hottie, go look at expensive cars, but Kristin's day of joyriding comes to a surprisingly abrupt halt, causing a nightmare no one expected.
When Morgan throws Christina an 18th-birthday bash, she cuts LC and Lo from the guest list, so bumping into them the next day at the nail salon was sweet irony. Christina and Morgan then head to NYC for their spring break trip. While Morgan soaks in the big city fashion, Christina is challenged by the audition of a lifetime.
It's spring break in Cabo and anything can happen, especially since LC, Stephen and Kristin are staying in the same hotel. Kristin's wild partying at a club prompts a fight with Stephen, opening the door for him to hook back up with LC.
After the craziness of Cabo, Kristin invites Stephen to a Blink 182 concert with the hope of getting back together. LC, Lo, Trey and Dieter also hit the show, and when an outsider insults LC and Lo's character, Trey steps up in their defense.
Things come to an end! Everyone leaves, couples and friends say a final goodbye. Laguna Beach would be what it is, when there wouldn't be a big surprise to the end.
