During the day, Katherine works in a publishing house, but as soon as the city falls asleep, the girl goes to the cemetery to resurrect the dead and give them one last chance to say goodbye to their families. But any magic has its price. Waking the dead is still a pleasure, especially when Katherine pays for the time spent by the deceased in the world of the living with her own life. One day, a girl is asked to perform a favor and get a magic clock from an unmarked grave. But, to Katherine's surprise, all she manages to find is the body of an unknown boy, who also comes to life and remembers nothing not only about his past, but also about the cause of death. This magic is stronger than any other with which Katherine had to deal. Now the girl has to find out how the missing watch and the unknown person are connected before time begins to play against her. But the difficulty is that Katherine's client is always dead.
