We couldn't find all that much online about this little nightmare of a short film, at least not in a language we understand. The director, writer and production duo behind the film, Marc Riba & Anna Solanas, seem to be the CEOs of I+G Stop Motion in Barcelona, "an independent production company specialized in stop motion animation and puppet animation." This short is a dark, nightmarish example of their mastery.
The storyline commonly found online is "Violeta loves best fishing into the darkest depths," which is little more than a play on the film's title, which translates into something like "Violeta, the fisherwoman of the dark sea." In the end, Violeta, la pescadora del mar negro is somewhat plotless; more than anything else, it is simply an oneiric, disturbing tableaux of dank and disturbing scenes that play out consecutively and interlink, but there is no real beginning or end to the narrative. Nothing is resolved or revealed in this short: what went on before, and what will transpire afterwards is a mystery — the only thing for sure is that it wasn't, and won't be, pleasant.
