In the year 2023, in Paris, the City of Lights, Alexia, Tam and Sylia reunite after a long period of separation. At the same time, a work of art that belonged to their father, who disappeared a decade earlier in a strange fire at his art gallery, reappears at a prestigious exhibition at the Eiffel Tower. They decide to risk everything to steal it, in the hope of finally finding out what happened to him. The trio soon find themselves in the sights of Quentin Chapuis, commander of the BRB (Brigade de Répression du Banditisme), with the mission of stopping these new burglars who are constantly slipping through his fingers. But what he doesn't know is that among them is Tam, his long-lost love... Between their emotional and chaotic reunion, their daily lives as modern young women and their new secret and dangerous enterprise, the three sisters will have to face every challenge.
