Anne, the beautiful princess and daughter of Don Florentin, loves to stroll among the people, constantly postponing her obligation to marry. One day, fate brings her together with Thomas, a humble artisan, beloved by the entire village and creator of beautiful guitars signed with a heart. A passionate love blossoms between them, immediately forbidden by Anne's father, who demands a jewel from suitors as proof of nobility, demonstrating his preference for the powerful and shadowy Duke of Aragon. But Thomas and Anne do not give up. With the help of their faithful companions, the generosity of the village, and the talent of a mysterious fugitive, they will use the art of jewelry to convince everyone that love is worth fighting for and that the Duke's designs are far more evil than they seem.
