Five girls from different Latin American countries join young men in a house in the Delta del Tigre. With a psychedelic presentation of the credits, the film's publicity announced it as “the first conditional screening film in Argentina”.

Anita Camacho, an ambitious maid poses as the owner of the house where she works in order to seduce a man of money, marry him and finally stop being poor.

Commissioner Leon (Miguel Angel Landa) investigates the murder of a woman in a population near the capital. The woman was raped before death and the case is complicated when his brother becomes the prime suspect, since it is a priest (Eduardo Serrano). Because of the implications that inquiries might have, Leon is pressured to keep the event as a "crab" (Cangrejo, or a unsolvable case), but he decides to comply with the law.
