"You are obese, Mrs. Moriarty."
Peggy Moriarty is stunned. She knows she's let herself go a bit, but she thinks her young, skinny doctor is exaggerating. Her husband's death fourteen years ago left her to raise their twins, Grace and Greg, alone. But now that they're teenagers, doing their own things, her only hobby is watching Messages from Beyond, a show about a medium who connects the grieving with their deceased loved ones.
When the twins leave for college, they give Peggy a gift certificate for an exercise class. At first, Peggy is insulted. But once the sting wears off, she realizes if she gets in shape, she might gain the confidence she needs to go on her favorite TV show and talk to her husband one last time.
With help from her new friends at the gym and Carmen Tavarez, the mother of Grace's boyfriend, Peggy begins to emerge from her prolonged grief and spread her wings. She may soon discover that her sum is more than a mother, a widow, and her body.
