Tasked with curating a world-class collection for the Pierpont Morgan Library, Belle rises to prominence, mingling with high society and becoming an influential figure in the art and literary world. Underneath her undeniable intellect and wit, however, lies a concealed truth. Belle is African American, passing as white by fabricating Portuguese heritage to navigate a prejudiced society.
