Students of the university of Salamanca are brutally murdered by a black masked minstrel. Alex, an architecture student who has recently moved to Salamanca discovers a pattern behind the killings; it seems as if the killer strikes regularly after the exams to free the campus from lousy students.

Maria, whose parents live in the country, cannot stand her father's authoritarian ways and moves to the city. She finds a job as a cleaner and tries to survive in a wretched apartment in the shabby part of a big city. She is pregnant, and the fact that her boyfriend has abandoned her does not help matters. When her father goes to the hospital for an operation, her mother comes to stay with her. Her neighbor, an old recluse whose only friend is his dog, begins to come out of his shell and these three lost souls try to give each other the strength to start over.
