Based on the true story of the "Lonely Hearts Murders," renowned director Arturo Ripstein’s Deep Crimson (Profundo Carmesí) is an emotionally charged and profoundly original take on serial killing. Nicolas Estrella has made a meager living seducing and then stealing from lonely, often widowed, women he meets through the personal ads in local newspapers. While trying to victimize Coral, a hefty, half-mad nurse obsessed with Estrella’s movie star looks, Nicolas can’t help falling in love with her merciless enthusiasm for his seedy lifestyle. Together, the pair roam the back roads of Mexico looking for lonely women who Nicolas seduces and the insanely jealous Coral then murders. These lovers turned assassins feed on the misery of others with each murder binding them together all the more closely until a pitiful confession from Nicolas prompts the pair’s fitting demise.
