In 1974, 11-year-olds Wendy, Jude, Kelly, and Nick play hide-and-seek in an abandoned convent. When 10-year-old Robin tries to join them, the group starts teasing her by repeating "Kill! Kill! Kill!", leading to a scared Robin accidentally falling to her death through an open window. Instead of reporting the incident to the police, the children make a pact not to tell anyone what happened and keep the incident a secret. A shadow falls across Robin's body, revealing that someone else saw the whole thing. Later, a known rapist is mistakenly blamed for Robin's death and is arrested.
