The Seth/Summer plan to help Ryan shake his Lindsay blues is...a mall visit? Hey, it can work. Because Marissa comes along. And everyone gets locked inside the place. An extortionist targets Julie.

$500,000 is still the going rate to keep Julie's porn past off the net. Meanwhile, Seth plays matchmaker, suggesting that Ryan help Marissa plan the school's spring bonfire. Someone's gonna get burned.

A new arrival at Newport Beach causes a stir, while Julie causes a stir of her own when her past finally catches up with her. Meanwhile, Kirsten and Carter grow closer, and Zach returns from his holiday claiming to be totally over Summer.
