A snowy New York City night — a beloved teacher — a shocking crime: this provocative drama pieces together the puzzle of a man’s life just before it changes forever. While on his way home one evening, Walter Zarrow [Sam Waterston] — a popular Columbia University philosophy professor, is violently attacked on the street. Flash back one week, as actor-director Tim Blake Nelson traces the domino effect of events that led up to this seemingly senseless assault. Along the way, hidden connections between a seemingly disparate group of people — including a self-destructive student [Kristen Stewart], a hard-drinking suburban housewife [Gretchen Mol], and a desperate junkie [K. Todd Freeman] — emerge, forming a complex, engrossing mosaic of lost souls united by tragedy. The stellar ensemble cast includes Glenn Close and Michael K. Williams.
