《桥下杀人事件》改编自蕾贝卡高佛瑞（Rebecca Godfrey）的同名畅销小说，以 1997 年的真实犯罪事件为灵感。

故事描述 14 岁的瑞娜维克（Reena Virk）在与朋友一同参加派对后，从此不见踪影。透过一位作家和当地警察的合作，走入青少女嫌疑犯们的世界，揭开看似不可能为犯案者的兇手，其背后隐藏的秘密。

"Under the Bridge” is based on acclaimed author Rebecca Godfrey’s book about the 1997 true story of fourteen-year old Reena Virk (Vritika Gupta) who went to join friends at a party and never returned home. Through the eyes of Godfrey (Riley Keough) and a local police officer (Lily Gladstone), the series takes us into the hidden world of the young girls accused of the murder — revealing startling truths about the unlikely killer.
