In the sleepy suburb of
Grosse Pointe, Michigan, a group of neighborhood boys—now grown men—reflect upon their memories of the five Lisbon sisters, ages 13 to 17, in 1975. Unattainable due to their overprotective Catholic parents, math teacher Ronald Lisbon and his homemaker wife Sara, the girls—Therese, Mary, Bonnie, Lux, and Cecilia—are enigmas who fill the boys' conversations and dreams. During the summer, the youngest sister, Cecilia, slits her wrist in a bathtub, but survives. Her therapist, Dr. Horniker, suggests to her parents that her suicide attempt was a cry for help, and she would benefit from wider interaction with her peers, particularly boys. Despite this, Mrs. Lisbon is unwilling to allow her daughters a normal social life. Mr. Lisbon persuades her to allow a chaperoned party to make Cecilia feel better. However, after other boys make fun of Joe, a teenager with Down syndrome, she excuses herself and commits suicide by leaping from her second-story bedroom window, impaling herself on a spiked iron fencepost below. Afterwards, the Lisbon parents watch over their remaining daughters even more closely. This further isolates the family and heightens the air of mystery surrounding the girls, particularly to the neighborhood boys. At the beginning of the new school year, Lux, the most rebellious sister, enters into a secret, short-lived romance with Trip Fontaine, the school heartthrob. In hopes of becoming closer to her, he comes over to the Lisbons' and watches television with the family. Trip persuades Mr. Lisbon to let him take Lux to the
homecoming dance by promising to provide dates for Therese, Mary and Bonnie, and going as a group, to which their parents agree, with Mr. Lisbon chaperoning the dance. After being voted homecoming king and queen, Trip persuades Lux to ditch their group and take a walk on the football field, where they have sex. Afterwards, she falls asleep and he abandons her. At dawn, Lux wakes up alone and takes a taxi home, where she is met by her distraught parents. Due to Lux breaking curfew, the girls are all punished, taken out of school and confined to the family home. By using flashlight signals and playing records over the telephone, they share their feelings with the group of neighborhood boys. Lux rebels and becomes promiscuous, having anonymous sexual encounters on her house's roof late at night with a succession of boys and men; the boys spy on her from across the street. After months of confinement, the sisters begin to leave notes outside for the boys. These culminate in a final note asking them to come over at midnight, ostensibly to help the Lisbon sisters escape from their house. When the boys finally arrive that night, they find Lux alone in the living room, smoking a cigarette. Thinking they are going to help the girls escape, the boys are invited inside by her to wait for her sisters while she goes to start the car. Curious, the boys wander into the basement after hearing a noise and discover Bonnie's body hanging from the rafters. Horrified, they rush back upstairs, only to stumble across the body of Mary in the kitchen, where she has put her head in the gas oven. The boys realize the girls have all killed themselves in an apparent
suicide pact: Therese overdosed on sleeping pills upstairs, and Lux died of
carbon monoxide poisoning by leaving the car engine running in the closed garage. Devastated by the suicides of all their children, Mr. and Mrs. Lisbon quietly flee the neighborhood and are never seen again. Mr. Lisbon has a coworker clean out the house and sell the family belongings in a yard sale; family photos and other mementos are put out with the trash and collected by the boys. The house is eventually sold to a young couple from Boston. Unsure of how to react to the events, the adults in the community go about their lives as if nothing traumatic happened, or even making fun of the suicides, but the boys cannot stop thinking about the Lisbon sisters and why they did what they did. Now adult men themselves, they acknowledge that they had loved the girls, and that the mystery surrounding their deaths will torment them for the rest of their lives. ==Cast==
