Nocturnos (2008)

Three stories that happen on a night apparently like any other in Buenos Aires and have something macabre in common. Román attends the farewell party of one of his co-workers looking to meet with Laura. Elizabeth, an exchange student from San Juan, arrives at the house of Nuria and Alberto, a very strange couple who live on the outskirts of the city. The Ramones, a criminal gang, go to a factory to carry out a job assigned to them by a commissioner.
