Chaganty keeps the tension tautly wound throughout, moving the narrative along at a brisk clip. There’s no fat on this lean thriller. There’s also not much in the way of surprises; you get exactly what you expect here. What keeps it engaging is the sharp editing, stellar suspense, and two lead performances that sell the hell out of a plot that could read as schlocky melodrama in lesser hands. It helps that it’s framed from Chloe’s perspective as she pieces everything together while under firm lock and key.
