The film takes place in Niebla, an actual town on the southern Chilean coast. Lucas has come from Santiago to visit his sister, a dentist at the local medical clinic, before he heads off to architecture school in Montreal. The area is full of old Spanish forts, which he goes around sketching. Antonio is a fisherman who dreams of owning his own boat, who also takes part in re-enactments of the victory Chilean rebels had over the Spanish in their war of independence. The two meet and fall in love.
While there is homophobia to deal with, the biggest problem with "happy forever" is their different visions of what life each wishes to lead.
The director made good use of the area's actual history. I have sailed the islands and channels of southern Chile, and the scenery brings back fond memories. The action is authentic - both between the principals, and in scenes of everyday life.
