Six schoolgirls in their early teens are confined to a sinister boarding school where they are intimidated and often abused by the nuns in charge of running the institution.
The school’s most dreaded nun discovers that one of the girls is pregnant. The outraged nun gives the girl a brutal beating; she pulls the helpless child into the bathroom and shoves the showerhead into her mouth, turning the water on full blast in order to ”purify“ the expectant child-mother. The girl’s five friends, prisoners of fear and rage, horrified witnesses to the cruel torture, decide to help their classmate.
The following day the nun is found dead.
14 years later, the six girls lead separate lives. Each one has chosen a different path, with the hope of forgetting about one and another, and bury their terrible secret from their past.
One of the girls is brutally assassinated. A few days later another a classmate is found dead under similar circumstances.
The remaining girls begin to associate the brutal killings, and seeing that their lives are in danger, decide to join forces after all these years, and confront their terrible secret, anguish, and reality. They have to get the NUN before she gets them.
They know she’s back for vengeance. And the only way to thwart her plan is to return to the scene of the tragic incident: the boarding school.
