Cecilia and her son Martín have a car accident. On the third day after the crash, she wanders by herself on a lonely route and there is no clue of her son. She can't remember what happened during this time and she is desperately looking for her son. On her quest she finds coincidences with her case and other police files, which seem to be acts of a brutal hunting. The circles goes round and Cecilia will end up facing a religious man, who is the responsible of this slaughter. For her, he is a lunatic. For him, Cecilia is the enemy.
