It's 1894. Jordan Wallace and Sadie Wagner appear to have little in common. Jordan, a middle-aged black teacher, lives in segregated Chicago. Two thousand miles away, Sadie, the white wife of an ambitious German businessman, lives in more tolerant Oakland, California. But years ago, their families intertwined on a plantation in Virginia. There, Jordan's and Sadie's mothers developed a bond stronger than blood, despite the fact that one was enslaved and the other was the privileged daughter of the plantation's owner.
