1947 Paris. Rising fashion designer Paul Sabine is offered the keys to Paris' fashion kingdom. But he can't do it alone. He needs the help of his volatile brother, Claude, the true genius behind the label. This secret will be kept at any price; but is not the only shadow that will threaten the atelier's fortunes and transform the lives of its work and blood family.
The new business marriage with Jules Trouvier, is only hours into its honeymoon, when he and Paul clash over how to run the house. With millions at stake, when Nina is thrust into the unlikely role of a couture model events take a darker turn. But Paul defends his family and his vision despite the risks and the personal cost.
Under pressure to create the Spring show, the Maison is a hive of activity, yet Claude is not creating, and Nina is focused on finding her child. US journalist Rossi returns to question Paul's former boss and mentor, forcing Paul to punish those he loves. Claude finds an unlikely new muse, at the same time as the sailor's dead body is discovered.
A detective arrives asking questions about the dead body found on Sabine property, while the pressure piles on Paul who has everything riding on the new show. When Nina's modelling debut is a triumph and Paul is lauded as the new fashion Prince, Claude must watch from the wings. But how long will he let his brother take bows for his work...
Paul's glory is short-lived and instead of basking in the afterglow of a jubilant show, he is questioned about the murder. The rest of the House are struggling with coming to terms with success, Nina and Billy have many questions, and Claude declares he's no longer happy to stay in the shadows. Is Paul's brother becoming a liability?
The inner circle of the Maison spend a weekend at Trouvier's chateau. But there, the Sabine family is rocked by an untimely revelation, surprising alliances, and relationships that may be damaged beyond repair. Paul will soon discover that a spurned, humiliated staff member may threaten his livelihood more than a mud-slinging reporter.
The mood is sombre following a staffer's road accident, and Helen's attempts to help using her family connections, only raises troubling wartime questions for Paul. Charlotte meanwhile begins her counter attack on the business and threatens to expose Claude as the true genius behind the Paul Sabine label.
The whirlwind of divisive events vexing the house of Paul Sabine reaches its climax. Paul fights to keep hold of his empire, while Yvette tries to broker relations between her sons. Nina and Billy must decide where their future lies, and amid a dazzling celebration at the Maison, the family and the business unravels behind the scenes.
