Thrown together for a school project, Jessie, Zarah, Rose and Shanice don't think they have much in common until they start moaning about their mad - and maddening! - mums (and a step-mother too in Jessie's case). When the girls jokingly decide to band together as the OMG! Support Group (Our Mums - Grr!) things quickly escalate and soon they are posting their frustrations on the OMG! blog. But the mums aren't best pleased when they find out...
Four 'good' girls meet in detention, and their embarrassment means that initially they don't hit it off.
