A couple's comfortable, if sometimes strained, routine is changed with the arrival of Pandora's big brother, Edison, who is three times the size he was when the siblings last saw each other. He is morbidly obese. Edison interjects himself into Pandora's world and forms a bond with Pandora’s stepchildren, opening doors to the past and to her parents that she would rather keep shut. Determined to keep her family together, Pandora embarks on a challenge: she’ll find an apartment for Edison, move in with him and support him financially, but only if he loses enough weight to resemble the person he once was.
