Anita Rocha da Silveira’s vibrantly morbid debut feature is a coming-of-age story in which passive aggression on the handball court, jealousy among friends, and teenage angst unfold in the foreground of a slasher flick. In Rio de Janeiro’s Barra da Tijuca—a newly formed upper-middle-class neighborhood of car-lined thoroughfares, gigantic malls, and monolithic white condos—a clique of teenage girls become fearfully captivated by a string of gruesome murders. The most fascinated is Bia (Valentina Herszage), whose own sexual discoveries evolve alongside the mounting deaths in this skewed world of wild colors and transformative desires. With nods to Brian De Palma’s Carrie, Jacques Tourneur’s Cat People, and the atmospheres of David Lynch, Rocha da Silveira’s contribution to the genre is nonetheless entirely her own.
