For many years... Julen and Ibai were inseparable. As friends they went to the same classes, played together in the garden, took walks along the beach on summer evenings. Now... Julen is just a teenager who wants to go unnoticed. Ibai has become a total stranger to him. However, everything changes because of a dream, a blood-red moon, a diary and a death. Now Julen must face a countdown where he will have to fight, make himself worthy and perhaps, give an opportunity to the most unlikely people. Perhaps he will be able to rewrite history and prevent a tragic death. To do so, however, he will have to get to the roots of his past and confront the shadows that obscure it, to understand how much a life matters and how much he is willing to trade in order to save it.
