It's 1912, the era of Jim Crow and lynchings. A young society woman learns that her grandfather, the grandfather she barely knows, may be passing for white. She has a family. She has a child. She can't be black. It will ruin all their lives. She follows him onto the newest, safest, biggest ship in the world to find a truth she can live with. But after the iceberg, she finds the truth is more than black and white. More loving, more inspiring, far more dangerous. And what she'll have to find is not a convenient truth, but a new America.
