With their senior year rapidly coming to an end, the Laguna Beach teenagers get ready for a summer filled with fun and drama.

As the love triangle growing between LC, Kristin, and Stephen becomes obvious, the three of them begin to feel the pressure.

LC, Trey and Stephen head to Los Angeles for a designer fashion show; while there, LC sees Stephen's attention wander from the fashion to the fashion models.

Morgan throws a spectacular party for Christina's 18th birthday and leaves LC and Lo off the guest list, before running into them at the nail salon the next day.

The crew spends its spring break in Cabo, and a fight between Kristin and Stephen leaves the door wide open for LC, who is staying in the same hotel.

Following the dramatic events in Cabo, Kristin hopes to reconcile with Stephen, and invites him to a Blink 182 concert; LC, Lo, Trey, and Dieter head to the same concert, and battle difficulties of their own.
