The Twelve Stars is the story of Herculano Fontes, a well-known astrologist, who met Destiny, who has come to propose an agreement. Herculaneum has to show his astrological expertise by meeting twelve women, each one ruled by one of the 12 Zodiac signs. If Herculaneum fails in his pursuit, he will die the imminent death in his astrological chart. If he fulfills his quest, he may interfere with his own destiny and change it at his desire.
