Plot
In the film, the story begins with three teenage boys breaking into the house of Ruben Borchardt with the intention of killing him for payment. The film then jumps back seven months earlier to the fall of 1993. Ruben's wife, Diane, is portrayed as mentally unstable and abusive towards Ruben and their children. Ruben meets Claire, a woman he develops feelings for, and they begin an affair. They contemplate leaving their spouses to be together.

Ruben decides to divorce Diane and gain custody of their children, which angers Diane. She manipulates her students, including Doug, to carry out her plan to kill Ruben. Diane bribes Doug with money and jewelry to carry out the murder. Doug recruits his friends Josh and Mike to help him. Diane continues to harass Claire and threatens her life.

Diane physically abuses Ruben and falsely accuses him of hitting her. They separate temporarily, and Diane plans to carry out the murder while she is away from the house on Easter Sunday. On that day, Doug and his friends break into Ruben's house, shoot him with a shotgun, and flee the scene. Ruben's son Chuck discovers his father bleeding and calls for help. Ruben dies in the hospital.

The police investigation begins, and they suspect Diane's involvement. They discover the photographs of Ruben and Claire together and question the boys who took the pictures. Doug struggles to get the money promised by Diane and eventually confesses his involvement to the police. Mike and Shannon are also arrested. Diane tries to conceal her guilt but is eventually arrested as well.

During the trials, Doug and Mike are charged with first-degree murder, Josh pleads guilty and testifies against the others, and Shannon is charged with perjury. Diane is found guilty of first-degree intentional homicide and breaks down in court. The Borchardt family, along with Brook's husband and newborn son, visit Ruben's grave and reflect on his life.

Production
Ulysses S. Grant High School in Los Angeles, California was used as the filming location for the external scenes at the high school where Diane Borchardt teaches.

During production, the names of several individuals involved in the case were deliberately changed for their purposes and those of the film.
