For many it is the pinnacle of faith, for others it is proof that even the Bible sometime goes wrong, when God calls Abraham and instructs him to prepare his son Isaac as a burnt offering. Abraham is an aging businessman. He lives on the Gold Coast in Chicago. One hot summer afternoon his wife Sarah tells him she is going to have a baby. Abraham assumes she is joking. Sarah insists otherwise, and to prove it five months later she delivers a baby boy as bald and wrinkled as his father. Isaac is a healthy child, Sarah a happy mother, Abraham a gruffly affectionate father. But will they be able to continue their ordinary lives, when God commands them to make such an extraordinary sacrifice?
