Season 12

Any hope of peace in the OC is shattered when a vicious rumor campaign destroys Vicki Gunvalson and Tamra Judge’s former friendship, a conflict worsened when returning peacemaker Lydia McLaughlin inadvertently sparks a feud with an emotionally overwhelmed Shannon Beador. As Shannon endures agonizing personal stress and the slow-motion collapse of her marriage, Kelly Dodd faces a similarly painful marital crossroads but works hard to build bridges and show a softer side to her old rivals. Adding to the tension is wealthy newcomer Peggy Sulahian, whose private health battle and defensive nature draw the immediate suspicion of new mother Meghan King Edmonds, stoking deep mistrust just as the women embark on a volatile vacation to Iceland.
