Zoologist Chloe was murdered by her husband Arthur and fed to a giant python. She was unexpectedly reborn and returned to the night before her murder. She pretended to obey, and teamed up with her best friend Victor to collect evidence that Arthur defrauded the insurance company and killed people, and set up a trap to let the python bite him back. During the investigation, Chloe was surprised to learn that Arthur's accomplice was actually her long-lost sister Mia. After a confrontation, she revealed that Arthur's accomplice was a fake person hired by Victor. Then Victor revealed his true face. He planned everything to resurrect his dead wife, artificially created Chloe's rebirth, and tried to use humans to extract neural enzymes. Chloe used her tricks to resolve the giant python and multiple crises in abandoned warehouses and laboratories, and finally captured Victor. Arthur kidnapped the hostage, planted explosives and resisted, but was subdued by the police. The storm ended and several people were punished by law. Chloe put aside her hatred, sold her scientific research patents and established the Violent Women's Assistance Foundation to complete her true self-rebirth.
