Female teacher Samantha (Geena Davis) lives a comfortable life in a quiet town with her 8-year-old daughter. She feels very satisfied with everything, except that she has lost some memory. In a car accident, her lost memory began to recover, and some fragments of her brain made her doubt her former identity. With the help of private detective Mickey (Samuel L. Jackson), Samantha learned that she was actually an FBI agent, and in the investigation bureau, an agent who accidentally learned the boss's secret is not welcome. The news that Samantha is still alive spreads wildly, and she can feel that some very cruel terrorists are gradually approaching her and her daughter. They have only one purpose, and that is to get rid of her as soon as possible.
