A Black family has recently moved into a new home in a not-so-safe neighborhood, but a routine evening is disrupted by an intruder. Chris (Nnamdi Asomugha, who directed and co-wrote the script with Mark Duplass) goes down to the kitchen to find the source of the noise. In his hand is a knife. Though he confronts the stranger, what exactly transpired between them is not shown onscreen. And so The Knife begins on an anxious, tense note that it delicately continues to escalate until the final moment, leaving us on edge throughout a swift, stress-inducing 82 minutes.
