A gripping portrait of women, whose lives were dictated by a moral code, Maria’s Grotto is a painful true film about the issue of honor killings in Palestine. Khoury explores the issue through the stories of four women: one is wrongly accused of dishonoring her family and then murdered; the second dies after being forced by her brothers to swallow poison; the third survives repeated stabbings inflicted by her brother; and the fourth is a Hip-hop singer who dares speak out about honor killings, and faces death threats. Through these stories, Khoury exposes the magnitude of honor killings in Palestine.
