Both family and community are shaken by the unexpected, tragic suicide of teenage girl Lucille Dillerton. Her friends at high school, June Thompson, Francine Van Pelt, and Sally Higgins, are devastated and discuss among them the reasons for their friend to jump off the pier into the river like she did. Lucille's death is investigated by the police, to rule out any alternative causes to Lucille's death, and in charge of the investigation is Lt. Hanahan. He arrives to the high school, and the principal, Mr. Moffatt, is ordered to call the girls into his office for questioning by the police officer. One of the girls, Sally, doesn't want to cooperate and answer the questions.
