In 2023 Paris, three sisters—Alexia, Tam, and Sylia—are reunited after years apart. Their father, a renowned art collector, died a decade earlier in a mysterious fire at his gallery. When a painting from his collection unexpectedly surfaces at a prestigious exhibition inside the Eiffel Tower, the sisters see an opportunity. They decide to steal the artwork, hoping it will lead them to the truth about their father's disappearance and the fire that claimed him.

The trio begins a double life as daring art thieves, orchestrating heists across the French capital's most iconic and secure locations, including the Louvre and the Palace of Versailles. Their quest puts them directly in the crosshairs of Quentin Chapuis, a determined commissioner with the French police's Organized Crime Unit. Tasked with capturing the elusive new thieves, Quentin is unaware that one of them is Tam, his former girlfriend and the great love of his life. This creates a tense cat-and-mouse dynamic as the sisters evade capture while navigating Tam's complicated feelings for the man hunting them.

As the sisters steal more works from their father's lost collection, they delve deeper into a conspiracy surrounding his death. The narrative follows their transformation into a cohesive team, balancing their normal lives with their dangerous clandestine activities. Supporting characters include Gwen Assaya, a perceptive police officer who grows suspicious of the sisters, and other figures from the art world and the police force who become entangled in the mystery. Each heist brings them closer to the truth about their father's fate and the shadowy forces behind the fire, culminating in a confrontation that resolves the first major chapter of their search.
