Each season documents the lives of a group of young people living in Laguna Beach, California and attending Laguna Beach High School. Casting would interview applicants about school, their social life, and any romantic interests in search of a story to document that would be of interest to the target audience. Cameras were not invited into the school, but a single camera was taken into formal dances usually by a cast member and some footage was used on-air. The only event to which cameras were allowed was graduation because it was in a public venue rather than the school itself.
