As their father descends into the long good-bye of Alzheimer's Disease, two brothers discover a shocking secret about the birth of one of them, and they're not sure which one it is. The eldest brother, a Presbyterian minister, is a devout man with a calm and steady demeanor. The younger, a hard-working racehorse veterinarian, is a brash, restless, bachelor workaholic.

The quest asks whether blood defines family, or if the bonds forged by love and sacrifice are what truly make a person belong.
