Plot

Rebecca is a young girl who, haunted by her father’s suicide, enrolls in an elite boarding school for girls. Before long, her friendship with the popular Lucy is shattered by the arrival of a dark and mysterious new student named Ernessa, whom Rebecca suspects may be responsible for the rising body count at the school.

Sinekatalog’s take

A grieving teenager at an elite school suspects a mysterious new girl of dark deeds. It has gothic atmosphere and some intriguing ideas about friendship and jealousy, but the scares are muted and the story flounders.Sinekatalog’s own editorial review – not a user or critic quote.
