Jacqueline Kennedy is beautiful, sophisticated… and contemplating leaving her young senator husband. Life in the public eye with an overly ambitious – and unfaithful – man who could hardly be coaxed to return from a vacation after the birth of their stillborn child is breaking her spirit. When she’s offered a holiday on the luxurious yacht owned by Aristotle Onassis, she says yes to a meeting that will ultimately change her life.

Maria Callas is at the height of her operatic career and widely considered to be the finest soprano in the world. And then she’s introduced to Aristotle Onassis, the world’s richest man and a fellow Greek. Stuck in a childless, sexless marriage, and with pressures from opera-house managers and a hostile press, she finds her life being turned upside down by this extremely intelligent and impeccably charming man.

Little by little, Maria’s and Jackie’s lives begin to overlap, and they come closer and closer until everything they know about the world changes on a dime.
