On her wedding day, Ava’s body weight spirals out of control, causing her wedding dress zipper to burst open right in front of the crowd. Her husband Julian openly shows his disgust, while the mocking guests taunt her as “a hippo in a wedding gown.” She fights back by splashing wine at the sneering crowd, only to be humiliated and harshly dismissed by Julian, provoked by his ex-girlfriend Camille. After chasing after her husband in the pouring rain with no avail, Ava hits rock bottom and chooses to join an extreme fitness bootcamp. Pushing herself past every limit, she survives thirty days of hellish training, transforming her oversized XXL figure into a toned, stunning silhouette. When her grandfather’s equestrian birthday competition kicks off, all the relatives and guests are still waiting to laugh at her disgrace—unaware that the old Ava is gone forever.
