Lubia, an undocumented immigrant from Guatemala, works for the Gallagher family, who live in a high-rise penthouse overlooking Central Park. Lubia is maid, cook, and wetnurse for the Gallaghers' son who, at seventeen, still nurses. To prove his manhood, he bottles and sells Lubia's breast milk, pocketing all the profits that literally flow from Lubia's body.
