After getting into a minor traffic accident, Pablo attempts to make light of the situation by asking the driver of the other car, Sonsoles, out on a date. When she refuses and instead files an injury report, Pablo snaps and begins stalking her. He soon discovers that Sonsoles has a beautiful teenage sister, Maria, with whom Pablo is immediately infatuated -- a lust that soon turns dark. Can Pablo control his obsession, or will it consume him?
