Love and death are similar, almost as though they were siblings. They differ in appearance, but they live together. El carrer de baix is a story of love and friendship, death and lack of affection which takes place in the city of Valencia and in Vall de Gallinera. In this valley, historically significant but with a low population, loneliness is wreaking havoc. This is where Joan, a school teacher, and Sara, a psychologist who farms terraces, live. Carlos, a book publisher, is also going to stay a while, trying to escape the pain caused by a foster child with delinquency and drug problems. Following the course of the Gallinera, a river that has all but disappeared, just like life in the valley, the three of them will share a path where the past and everything they have been unable to or not known how to avoid flows.
