Jessica (Kim Basinger), a female high school nature teacher, was kidnapped. Fortunately, there was an old-fashioned dial-up telephone where the gangsters imprisoned her. In panic, Jessica dialed a random number for help, and her emergency call came to the cell phone of the young man Ryan (Chris Evans). Ryan thought it was a prank at first, but then the gangster discovered Jessica calling for help and smashed the phone. After hearing the gangster's roar and Jessica's exclamation, Ryan realized the seriousness of the situation. After the gangsters left, Jessica used her knowledge of nature classes to reassemble the phone and get in touch with Ryan again. Through her story, Ryan learned that the gangsters would soon kill her husband and son, and Jessica didn't even know where she was. There is not much time left for Ryan, not to mention the limited battery of his mobile phone. Ryan must do everything he can to save the lives of Jessica's family.
