Rubiales, Rafita, Quinto, Caña and Lagarta are the members of a youth gang that has specialized in raping young girls. The four boys and the girl look for their victims at the exits of the schools and they lead them to some vacant lot where, immobilizing them, each and every one of them systematically violates the helpless victim. Dana, a young woman belonging to a family of the high bourgeoisie, suffers the attack of the band and as a consequence, gets pregnant. The trauma that Dana suffers due to the violent aggression, plus the news that she expects a son leads her to almost madness.
