Amber is one of the best thieves in the world. After a heist that doesn't turn out as expected, her new target is Isla Esperanza. There she is on a mission to steal the Tiara of Santa Águeda, a cursed and very valuable jewel, which Lucia Villegas will wear on her wedding day. Everything is calculated to the millimetre; Amber has been infiltrating the family for almost a year so as not to arouse suspicion. Until Rui, a brilliant thief with whom she had a love affair in the past, reappears on the island, forcing her to improvise. Together they will be forced to recruit a band of inexperienced thieves to orchestrate a new plan. In this game of deception, flight and betrayal, the greatest challenge will not be to steal the tiara, but to dare to trust each other.
