Film in two cities divided by one river: Buenos Aires, Montevideo. Two cities divided by one story: the death of Francisco. One death divided in two parts: an investigation, an escape.

I swear to you that this that I am going to tell is absolutely true: a daring sparrow, a girl who smokes cigarettes, a forest and Julián, in January in Buenos Aires.
