Lucia is a mature woman who maintains a relationship with the young John. When he is found murdered in a bullring with a nail stuck in his chest, Lucia is the prime suspect, it is believed that the motive for the crime was jealousy because it felt for her daughter Marta, which had also been seduced by John.

Hector travels with Luisa by the road linking Madrid with Barcelona. When another car suddenly crosses his path, his vehicle leaves the road and plunges into a tree. Hector dies and she is seriously injured. The other car was occupied by Jorge and Paula, her lover. Several vehicles cross before the car crash and do not stop, each for a different reason. Among them is Julio, a truck driver who does not stop in order to reach his destination on time, not knowing that at the wrecked car travels his old girlfriend.

In a sector of Madrid inhabited by families of a well-off class, a gang of boys and girls has continuous fun, sleep and drink, while their parents ignore practically everything. However, each of these young people has, to a greater or lesser degree, a problem. The parties and parties enjoyed by a group of young people from the upper class are the basis of the story that explains this film. Among them we find the famous couple, once happy, formed by Carlos Larrañaga and María Luisa Merlo. Directed by Fernando Palacios, and with a script by Rafael J. Salvia and Pedro Masó, " It's always Sunday " has no greater intention than entertainment, despite giving history a certain sociological touch, for that of valuing the behavior of the Youth of the time.
