Kevin Clayton wanted to be thin and attractive and to wear normal sized clothing. However, after rising to prominence as a fitness guru following an extraordinary transformation, he finds that happiness remains elusive. His marriage to his childhood sweetheart shattered, his relationship with his daughter destroyed, and unable to trust the countless women who swoon over him because of his new looks, Kevin struggles to find meaning for his accomplishment and his efforts to teach others how to change their lifestyle and lose weight. Ultimately, Kevin is torn between pursuing his ex-wife, Jennifer, or yielding to the advances of his sexy young assistant, Mika, whose motives are questioned when he discovers that she and a trusted ally, his trainer, Johnny, may be responsible for manipulating more than his diet.
