Debut: Malibu teens clash with their counterparts from L.A.'s San Fernando Valley. The opener centers on the star-crossed romance between Chloe and Zack --- which fans flames of anger and jealousy on both sides of the hill.

Teddy foolishly risks his life to hang out with the macho guys at school; Chloe gets stood up by Zack, who comforts his ex, Kacey; Kacey's tough facade crumbles under fierce razzing by her new schoolmates; and Flipper's older brother pays a surprise visit.

A popular art teacher chooses Chloe's design for a sea-wall mural for reasons that have little to do with art; Josh suspects that the play is not the only thing going on between rehearsing thespians Nina and Teddy; Flipper investigates off-beat story ideas for a creative-writing assignment; and the chemistry intensifies between neighbors Marc and Suki.

Chloe offers nothing but a chilly reception when her dad shows up unexpectedly at the house, but Josh is taken in by the man's empty promises. Meanwhile, other circumstances force Josh to take a hard look at himself-and his drinking; and a classmate's remorse encourages Kacey to reconsider Pacific Coast High.

Zack resorts to extremes to compete in English class; and Kacey covers her shame with puzzling behavior. Elsewhere, while Nina is away with the debate team, a calculating Ashley moves in on Josh; and Flipper goes overboard to get attention.

A competition for class president turns ugly for Zack and Chloe; a waitress helps Josh forget Nina; Ashley can't please her perfectionist mom.

Mouse gets mixed up with his brother's gang pals, who make trouble for Mouse and his friends.

Chloe baffles Zack by being secretive and pushing him away; and Nina sends the wrong signals to a hunky jock.

Chloe reluctantly enters rehab to treat her life-threatening habit; Teddy takes matters into his own hands after learning of Nina's encounter with Eric.
