Deirdre Griffin has a great life; it’s just not her own. She’s the around-the-clock personal assistant to her charismatic, high-maintenance, New Age guru brother, Tag. As the family wallflower, her only worth seems to be as gatekeeper to Tag at his New England seaside compound. Then Deirdre’s sometime boyfriend informs her that he is marrying another woman, who just happens to be having the baby he told Deirdre he never wanted. While drowning her sorrows in Tag's expensive vodka, Deirdre decides to use his massive online following to get herself voted on as a last-minute Dancing with the Stars replacement. It’ll get her back in shape, mentally and physically. It might even get her a life of her own. Deirdre’s fifteen minutes of fame have just begun.
