An innocent bachelorette dare goes horribly and violently out of control in Artemio Narro's first independent Mexican thriller, "If He Hollers." It all starts off innocently, with Natalia arriving in Mexico from Spain to visit her boyfriend (Diego Luna, star of "Y Tu Mama Tambien"). However, things suddenly turn dark after Natalia and her group of party animal friends meet an unsuspecting cowboy. The giggling girls secretly feed the macho man some Viagra and what began as a prank quickly turns violent. The story begins as an innocent comedy, with rich girls having carefree fun, it then undergoes a transformation that ends in dark sadism.
