A young scriptwriter meets a producer to sell him a film project based on an ancient Compostela legend that she wrote. The shadow of an uncertain and chilling evil looms over both when the rich and successful producer discovers that the plot resembles in a disturbing way his own life. This puzzle will unite the two characters in a dramatic way. Trece badaladas is a narrative of terror and metaphysics, between the Gothic novel and that of ideas and an inquiry about the memory of a city, Santiago.
