'The Proper Care & Feeding of an American Messiah' is the mockumentary story of a man who thinks he is a messiah. Not *the* messiah, but rather a local, regionally selected messiah for his own home-town. He's on a quest, desperately trying to raise money for a town-wide rally where he hopes to announce his deity - and to determine his true, god-given 'special purpose' in life - which may or may not have something to do with ailments of the lower gastrointestinal tract, but he won't be sure until he hears more or less directly from Yahweh.

Emmy Ferguson is a 10-year old who learns that, after a long bout with leukemia, today is probably her last day on earth. Chris Ryan is a 35-year-old drug addict who is determined to make this his last day. And Adonna Frost, suffering from advanced breast cancer, has made a similar decision about the end of her life. They are all strangers to each other, but as Emmy embarks on a strange journey, and as the day's events bring these three dying people together, through Emmy's unique point of view, their lives are changed forever.
