Four friends plan an excursion to some lakes in the Pyrenees. Before beginning the excursion, they visit their friend Carlos, a historian who lives in the area doing some research. Then, he tells them that he has found an ancient scroll which leads to the cursed cemetery sought by many explorers. The cemetery is called "The cemetery of the 24 steps", where, according to a legend, someone buried "the fisher's medal", a medal with an incalculable value. The four friends will find themselves inside a dangerous adventure when they try to find it.
