In Florida, when Liza graduates in Law School and Information of Technology, she will join the FBI. Her parents go with her to a sushi restaurant to celebrate, but a truck hits their car, and they die in the accident. One year later, Liza is paralytic in a wheelchair and has tried to commit suicide twice. She has physical therapy with Jeff, who is her only friend. Liza spends the days in Internet and one day she witnesses a man burning a dog in a barbecue. She calls the police and Detective Tim Boyle tells her that it is a misdemeanor, and he can do nothing since the user has deleted his account. Then she sees the same man killing a victim and she calls Det. Boyle again. He tells her that he will investigate but it will be difficult to find the man and it may be a hoax. On the third night, she sees the man killing another victim using a power drill and this time she records the scene. Det. Boyle comes with his former partner, the retired Agent Larry Thurgood, and they ask Liza to stop her investigation since she is not a sleuth. But Liza does not give up to try to find the killer using Internet.
