The title designates time and location: an unusually hot August in a rural area outside
Pawhuska, Oklahoma, 60 miles Northwest of
Tulsa. Beverly Weston, an alcoholic, once-noted poet, teacher and author, interviews and hires a young
Cheyenne woman, Johnna, as a live-in cook and caregiver for his strong-willed and contentious wife Violet, who has oral cancer and an addiction to narcotics. Shortly after this, he disappears from the house, and Violet calls her sister and daughters for support. Her sister Mattie Fae arrives with her husband Charles "Charlie" Aiken. Violet's middle daughter Ivy is single and the only one living locally; Barbara, her oldest, who has inherited her mother's mean streak, arrives from Colorado with her husband Bill and 14-year-old daughter Jean. Barbara and Bill are separated, but they put up a united front for Violet. After five days, the sheriff arrives with the news that Beverly took his boat out on the lake and has drowned. Youngest daughter Karen arrives with the latest in a string of boyfriends, Steve Huberbrecht, a sleazy Florida businessman whom she introduces as her fiancé. Mattie Fae and Charles's 37-year-old awkward son "Little Charles" misses the funeral because he overslept and is met at the bus station by his father. Charlie loves his son, whereas Mattie Fae constantly belittles him. Ivy confides to her sisters that she is in love with Little Charles, her cousin, who plans to move to New York, and that she cannot have children because she had a hysterectomy. She feels this is her only chance to finally marry. The family sits down to dinner after the funeral; fueled by drugs, Violet insults and embarrasses each person at the table under the guise of "truth-telling", which results in Barbara pouncing on her in a fit of anger. Barbara has had enough of her mother's drug addiction, attacks her, knocks her to the ground, and confiscates her multitude of pills. Later, after Violet has had a chance to sober up, she has a tender moment with her daughters and shares a story that demonstrates how cruel her own mother was when she longed for a new pair of cowgirl boots when she was in her early teens. Instead of giving Violet the boots she wanted, her mother gave her a beautifully wrapped box on Christmas morning containing old, filthy men's work boots as a cruel prank. The next day, when Little Charles sings Ivy a song he has written for her, Mattie Fae walks in and berates him. This exhausts Charlie's patience with his wife's lack of love and compassion for her own son, and he threatens to leave her if she keeps it up. Mattie Fae subsequently reveals to Barbara, who unintentionally listened in, that long ago she had an affair with Beverly, and Little Charles is in fact their younger half-brother as well as their cousin and that is the true reason why he and Ivy cannot be together. That evening, Steve and Jean are sharing a joint. Steve comes on to Jean, gets her stoned, asks her to show him her breasts, and starts to assault her. Johnna is woken by their conversation, sees this, and attacks him with a shovel. The commotion wakes up Barbara, Bill, and Karen who rush outside. Barbara confronts Jean and slaps her. This compels Bill to take Jean back to Colorado, leaving Barbara. Karen refuses to admit that her relationship is doomed and also leaves with Steve. Later, Ivy tries to tell her mother about her relationship with Little Charles. Barbara tries to deflect the admission to protect Ivy from the truth. Violet tells Ivy that Charles is actually her brother, something Violet knew all along. Devastated, Ivy leaves and promises to never come back. In the last confrontation between Violet and Barbara, Violet admits she was contacted by Beverly from his motel the week after he had left home but did nothing to help him until after she removed money from the couple's joint safe deposit box. By that time, he had already killed himself. This revelation leads Barbara to depart, realizing that her mother is far beyond help. Violet is left with only Johnna. Violet begins dancing to loud music but quickly becomes too upset and goes off to find Johnna for comfort. Barbara, driving through the plains, pulls off the road, gets out of her pickup, and cries. She then gets back in the truck and continues west, following signage showing highways and number of miles to Wichita, Salina, and Denver. ==Cast==
