Laura Pehlke is married to Bob and together they raise their 12-year-old son, Dennis. Laura is a dental hygienist and Bob works in a real estate office and often comes home late. The family goes to a birthday barbecue for Laura's twin niece and nephew. Laura suspects Bob is cheating on her and they get into a fight. She runs away from the house and Bob runs after her and suddenly collapses on the road. After a brief examination, the doctor says Bob has had a panic attack. Later that night, Laura begins to perform fellatio on Bob during which he has another attack from which he dies, and his condition is later diagnosed as arrhythmia.
Laura's sister, Kathy Helms, and mother Joan, are overbearing in their attempts to help Laura manage her life. Kathy insists Laura go to a lawyer to discuss her economic state. The lawyer claims the only way to get by with the money they have is to sue the doctor. Reluctantly, Laura cooperates. During the process, Bob's secretary admits to having an affair with him.
Laura's nephew, Kyle Helms, is an enthusiastic guitarist, and his father, Paul, supports him but Kathy thinks it hinders his academic future. She dismisses the garage band Kyle formed with his friends. Paul, a radio station employee, takes Kyle with him to see Dion DiMucci, who is visiting the station. After the program Kyle and Dion meet and play together.
Dennis moves to a private school on the insistence of Joan. In order to gain popularity with the kids at the new school, he lies and says his father died in the September 11 attacks while saving lives as a fireman. Laura confronts her son and criticizes his lying but he persuades her to back up his story and she ends up repeating the story to his class.
Dennis goes to a friend's birthday party, where he gets a body painting of the burning World Trade Center on his back. A kid who knew Dennis from summer camp happens to be at the party and he tells the other kids Dennis has been lying. Meanwhile, Laura coincidentally meets the birthday kid's mom at a gas station, and learns of the camp friend attending the party. Realizing the truth about Dennis' father will come out, she rushes to the party, but arriving too late to prevent the damage, finds her son sitting alone and crying, ostracized by the group.
One night Paul and Laura happen to be in the yard together, where they smoke pot and talk. Paul confesses he has had a crush on Laura since school and he married Kathy just to get something similar to Laura, which turned out to be a mistake. Back in high school he tried to get her attention by throwing a tennis ball over the fence and asking her for "a little help" by returning the ball. Some days later, Laura calls Paul at work and invites him to meet her. She tells Paul she regrets not returning the balls back in high school, because now she feels about him like he felt about her. She moves away a little, he comes after her, tells her she is beautiful, and they kiss.
As events unfold, Laura eventually has a breakthrough moment and we see her begin to take control of her own life, and the beginning of her healing and moving on.
