When the gang heads to The Bait Shop to see the British rock band THE SUBWAYS (themselves), Taylor's behavior causes a major rift between Seth and Summer. Determined to end the potentially explosive conflict between Ryan and Kevin Volchok (recurring guest star CAM GIGANDET), Marissa watches out for Ryan. Meanwhile, Matt (recurring guest star JEFF HEPHNER), Sandy's Newport Group partner, goes above and beyond the call of duty. Julie reigns supreme as the only bitch in Orange County, and for once, Ryan must control his anger.

Ryan makes a life-changing decision that Sandy surprisingly supports, and Marissa turns to her new public school friends for help with Ryan. The Harbor School's Dean of Discipline, Dean Hess (recurring guest star ERIC MABIUS), continues his crusade to ruin Ryan's future, and Summer and Seth go on their own crusade to reveal Dean Hess's secret. Meanwhile, Charlotte (recurring guest star JERI RYAN) makes Julie an offer she cannot refuse.

Marissa adjusts to life in her new surroundings and makes some new friends at Newport Union, while Ryan wonders how their separation will affect their relationship. Seth's feud with Dean Hess (recurring guest star ERIC MABIUS) lands Summer in trouble, but some startling new information about Taylor (recurring guest star AUTUMN REESER) may turn the tables once more. Kirsten's friend Charlotte (recurring guest star JERI RYAN) lands in Newport with some big ideas, while Sandy mulls over the future of the Newport Group. Meanwhile, Julie may no longer be a Newport Beach socialite.
