It's the opening weekend of deer season in Gunthrum, Nebraska, in 1985, and Alma Costagan's intellectually disabled farmhand, Hal Bullard, has gone hunting with some of the locals, leaving her in a huff. That same weekend, a teenage girl goes missing, and Hal returns with a flimsy story about the blood in his truck and a dent near the headlight. When the situation escalates from that of a missing girl to something more sinister, Alma and her husband are forced to confront what Hal might be capable of, as rumors fly and townspeople see Hal's violent past in a new light.

A drama about the complicated relationships connecting the residents of a small-town farming community, Deer Season explores troubling questions about how far people will go to safeguard the ones they love and what it means to be a family.
