"Whity" is the mulatto butler of the dysfunctional Nicholson family in the American Southwest in 1878. The father, Ben Nicholson, has an attractive young wife, Katherine, and two sons by a previous marriage: the homosexual Frank and the feeble-minded Davy. Whity tries to carry out all their orders, however demeaning, until various family members ask him to kill some of the others.
