Daniel Sanz, an archivist accustomed to the quiet rhythm of forgotten histories, begins to notice subtle disruptions in his life: red threads tied to doors, cryptic notes left in unexpected places, and a pocket watch running strangely out of sync. These quiet mysteries lead him toward questions he's long avoided—about his fractured relationship with his brother, the weight of a family home filled with memories, and the future he's been too hesitant to claim.

With the help of Irene, a perceptive colleague, Daniel uncovers a web of hidden connections that intertwine the past and present. As the threads tighten, he must decide whether to embrace the signs guiding him or remain trapped by the ghosts of what could have been.
