Killing Mr. Griffin
Brian Griffin is a strict high school English teacher at Del Norte High School in Albuquerque, New Mexico who never accepts late homework and is demanding of his students. When Mark Kinney, one of the students in his class, plagiarizes a paper Mr. Griffin makes him beg to be allowed back into the class. However, instead of allowing him back in, Mr. Griffin decides to make him repeat the class next semester. Fellow students in the class include David Ruggles, Jeff Garrett, Betsy Cline, and Susan McConnell. Mark suggests kidnapping Mr. Griffin, and convinces David, Jeff, and Betsy to join in on the plan as a way of scaring him and getting revenge because they feel he has treated them poorly.
The group decides to use Susan, who is least willing to participate in the plot, to distract Mr. Griffin by requesting a conference with him after school. Since Susan is one of his better-performing students with a serious approach to her studies, Mr. Griffin willingly does so, allowing her to walk him to his car afterwards. Jeff, David and Mark forcefully place a bag over Mr. Griffin's head and tie him up, replacing the bag with a blindfold as they take him to a remote spot in the mountains. Betsy, thanks to a speeding ticket, arrives in the parking lot after the boys have left with Mr. Griffin. Susan was supposed to ride with Betsy, but does not want any further part in the scheme and Betsy leaves without her. Mark tells Mr. Griffin to beg but he refuses, so the students decide to leave him alone there until midnight.
Susan and David defy the group and go check on Mr. Griffin. The two find him dead as a result of coronary arrest after being unable to take his medication for angina. Mark convinces the rest of the group to cover up the death. He instructs Susan, who was the last one known to the police to see Mr. Griffin, to tell them Mr. Griffin kept looking at his watch during the conference and left with a pretty woman. Jeff, Mark, and David bury the body in the mountains. Betsy and David also drive Mr. Griffin's car to the airport, but the officer who gave Betsy a ticket sees her there. Worried that the officer might later identify the car as Mr. Griffin's, Jeff and Betsy move the car into Jeff's garage so he can repaint it before they hide it elsewhere.
Mark's ex-girlfriend, Lana Turnboldt, has a picnic with her fiancé at the secluded place in the mountains, where they discover Mr. Griffin's medicine bottle. The police investigate, and find Mr. Griffin's body buried nearby. However, police do not find the ring Mr. Griffin was wearing when he died as David had taken it. Irma Ruggles, David's paternal grandmother who lives with him, discovers the ring and refuses to give it back to him, believing the ring to be that of David's father who had left him. David tells Susan he took the ring and his grandmother found it, but they are unsuccessful at retrieving it from her, so Susan tells Mark about the situation because she feels he would know what to do. Irma Ruggles is later murdered, and a neighbor refers to the suspect as a boy in a brown sweater. Susan makes the connection, knowing that Mark has a brown sweater he wears all the time, and that Mark would stop at nothing to get what he needed – in this case, the ring.
Susan plans to tell the police all that the group has done. Before she can inform the police, Mark, Jeff, and Betsy tie Susan up, and Jeff and Betsy leave to hide Mr. Griffin's car. Mark sets her curtains on fire but Susan is saved by Kathy Griffin, Mr. Griffin's wife, who came over to her house with a detective for an interview. The detective catches Mark as he attempts to leave the house through a window. Several days later, Susan's mother tells her that all of those involved will face varying criminal charges, with her lawyer attempting to get Susan off with no charges in exchange for testimony. Mark will face three trials, one each for the deaths of Mr. Griffin and David's grandmother, and one for the attempted murder of Susan. Kathy Griffin leaves Susan a note that her husband had written before his death, praising Susan for her work and recognizing her potential.
