Sisters Luzmila and Peta are housemaids at the side-by-side mansions of sisters Carmen and Alicia, two gossipy Peruvian aristocrats who have summoned their extended families for a big birthday bash. In writer-director Javier Fuentes-León’s boisterous and barbed social comedy, this celebration – unfolding as raucous political demonstrations clog the Lima streets outside their walled estates – devolves into open class warfare as amorous entanglements and long-buried secrets explode the party with hilariously chaotic results. Among the guests are a weed-smoking grandma and a gay son who arrives from Spain with his fiancée and, to the astonishment of his former lover, announces his plans to wed a woman. Fuentes-León (who made the groundbreaking 2009 queer Peruvian drama Undertow) choreographs the mayhem with expert farcical timing, skewering the pretensions and prejudices of his blinkered characters with a beguiling mixture of savagery and affection.
