Luna is a young woman who lives under the suggestion of dreams related to the disappearance of her father who was diagnosed as schizophrenic. After 10 years of his disappearance, his problems are accentuated and due to the insistence of Alba, her mother, agrees to undergo a therapy with Gael, a psychiatrist who was friend of his father with whom he shared a sailboat.
Gael has returned to Ibiza to try to start a relationship with Alba and recover the "Vagamar".
The dreams, sensations, allucinations and memories of Luna, embodied in a dress and a seashell, dismantle Gael's tactics and confront Alba's wishes.
Through Luna, R.E.M. leads us on a dream path where we discover some of the dreams most appealed by our culture and discover the problem between our conscious and unconscious.

In the "demi-monde" of night fishing, anglers on a French beach cast their lines. The camera follows their night-long toiling in obscurity, the contrast provided by the limited light sources resembling a scene from a baroque painting. Thus, a relatively ordinary activity takes on an otherworldly aspect, becoming an allegory for contemporary existence as well as for artistic production itself. For me, the situation evokes Miltonian-style scenarios of humans and rebel angels cast out of paradise and the film plays on Biblical fishing-related allusions (several of the apostles were said to be fisherman, and were described as ‘‘Fishers of men’’ and Christ was symbolized by a fish). Therefore, on a symbolic level, in the film the fishermen produce a ‘‘divine’’ signifier (i.e. the fish) which is subsequently disposed of, presumably leaving them to cast around for alternative significations. 

A lonely boat wanders around aimlessly in the fog, which has unexpectedly rolled up. The engine has stopped working and the visibility is as clear as the relationship between the father and son, who sit in the boat. What happens when these two are faced with an inexplicable threat?
