Amanda Vaughn, the ultimate mean girl in high school, is forced to return home in embarrassment after her marriage ends in turmoil. Despite her reluctance, Amanda has no option but to seek assistance from her mother, Gigi.

Amanda is concerned that Laura will be labelled as unattractive at school; Gigi hosts a party to reintroduce Amanda to society; Blake and Cricket dispute; Carlene plans revenge on Amanda; Sharon thinks about Zach.

Amanda is forced to face her history at a seminar; Heather pursues Andrew, a former high school geek; and Carlene interferes with Cricket and Sharon's relationships to distract herself from her marital problems.

Gigi throws a party for Carlene's uncle and encourages people to dress up as their ideal Texan; Amanda is a consultant for Cricket and Blake's denim line; Zack and Sharon seek professional help.

Heather gets Sheryl Crow to participate in the annual church gala with a bit of support from her new beau; Amanda and Carlene discover a new excuse to not get along.

Sharon is enraged when Luke persuades Carlene to steal Sharon's Matron of Honor responsibilities and assign them to Amanda for her 'Gone With the Wind' inspired renewal of marital vows.
