Other user already wrote about the wrong translation in the title. "Los fuertes" means the forts. This films is about conquering the other part and leaving their mark. You can see that on how one of the main characters changes the other, for example the way he is not used to "sleep like that". Everything could be magnificent, except that the doomed ending could be predicted from the start. That also leaves a false scar on how gay relationships are always short and fated. To contrast thatidea there in an openness between the main characters is daring and tries make a step forward in the Chilean cinematography. True and honest, just watch it.
