Sicario opens on a power chord of fear, nausea, and dread that resonates throughout the whole movie. After an introductory screen defining the title—it’s drug-cartel slang for hit man—the seventh feature film from Québécois director Denis Villeneuve (Incendies, Prisoners, Enemy) drops the viewer straight into the noise and chaos of a tense FBI raid on a cartel-owned house near Phoenix. The electronic soundtrack (by Icelandic composer Jóhann Jóhannsson) delivers a series of jolting sonic booms as a young field agent, Kate Macer (Emily Blunt), leads her team to an unexpected and macabre discovery: hidden in the walls of the house are dozens of decomposing bodies.
