At 400 pounds, Billy Brennan can always count on food. Food has always made everything better, until the day Billy’s beloved son, Michael, takes his own life. Billy determines to make a difference in Michael's memory and undertakes a public weight-loss campaign, to raise money for suicide prevention --- his first step in an ambitious plan to save himself and others. However, Billy's dramatic crusade appalls his family, who want to simply try to go on, quietly and privately. Despite his crushing detractors, Billy gains welcome allies, including his community-at-large and a co-worker who lost his father to suicide. But it is only if Billy can confront the truth of the suffering and brokenness within and around him that he and others will be able to realize the recovery they need.
