Upon investigating, Callie discovers the well is actually part of an abandoned Cold War experiment—a sophisticated resonance chamber designed to extract information directly from human minds. When Callie herself hears voices revealing her deepest secrets, she realizes the technology is still active and dangerous. Despite opposition from Sheriff Dina Ward, who has been protecting the site to preserve hope of finding her long-missing mother, Callie and Travis persist. In a tense showdown, Callie uses modern technology to overload the chamber system, successfully rescuing Travis's father and other missing townspeople. The government arrives to properly dismantle the facility, but a final ominous message suggests the voices might someday "resonate again." Callie departs with mixed feelings, committed to telling the victims' stories while acknowledging the dangerous allure of forbidden knowledge.
