Lily, a ten-year-old girl, has been labeled a liar since birth by her mother, who relies on a so-called lie-detection bracelet. Whenever Lily speaks the truth—whether she’s hungry, hurt, or innocent—the bracelet flashes red and shocks her brutally. Meanwhile, her twin sister Ruby wears a fake bracelet that glows green nonstop, even as she frames Lily for theft and destruction. Blinded by pseudoscience and favoritism, Mom locks Lily away, ignores her agony, and showers love on Ruby. On New Year’s Eve, Lily suffers a ruptured appendix, begging for help as the bracelet blares red; Mom calls it a tantrum, locks her alone, and goes to watch fireworks. Lily dies in agony, writing her last truth in a diary before her body goes cold. Three days later, Mom discovers the corpse, the diary, and the bracelet’s cruel secret: it only detects fear and pain, not lies. Ruby’s “honest” green bracelet is just a worthless toy. Wearing the bloodstained bracelet herself, Mom is shocked repeatedly as red lights expose her own lies. Consumed by guilt, she goes mad, tortures herself, and later attacks the scheming Ruby, who is hit by a truck and crippled. Dad loses everything and dies in despair. In the end, Mom passes away clutching Lily’s diary, while Lily’s spirit breaks free from the bracelet’s nightmare, floating to eternal peace—no more pain, no more lies, only freedom.
