No, the recent movie Amber Alert (2012) is fictional.
While filming their audition video for a popular reality television show, best friends Nate and Samantha notice several active AMBER Alert signs. To their surprise, they recognize the car traveling in front of them as the vehicle described on the AMBER Alert. Sam and Nate decide to follow the car, but with police slow to respond, their pursuit quickly turns into a high-stakes game of cat and mouse with a murderous child rapist.
But the movie Amber's Story (2006) is based on a true event.
The movie tells of the abduction and murder of Amber Hagerman
On January 13, 1996, nine-year-old Amber Hagerman was abducted while riding her bicycle in Arlington, Texas. A neighbor who witnessed the abduction called the police, and Amber's brother, Ricky, went home to tell his mother and grandparents what happened. On hearing the news, Amber's father, Richard, called Marc Klaas, whose daughter, Polly, had been abducted and murdered in 1993.
Richard Hagerman and Amber's mother Donna Whitson called the news media and the FBI. The Whitsons and their neighbors began searching for Amber. Four days after the abduction, a man walking his dog found Amber's body in a storm drainage ditch. Her killer was never found causing her homicide to remain unsolved. Her parents soon established People Against Sex Offenders (P.A.S.O.). They collected signatures hoping to force the Texas Legislature into passing more stringent laws to protect children.
God's Place International Church soon donated office space for the organization, and as the search for Amber's killer continued, P.A.S.O. received almost-daily coverage in local media. Companies donated various office supplies, including computer and Internet service. Local Congressman Martin Frost, with the help of Marc Klaas, drafted the Amber Hagerman Child Protection Act. President Bill Clinton signed it into law in October 1996.
In July 1996, Bruce Seybert[clarification needed] and Richard Hagerman attended a media symposium in Arlington. Although Richard had remarks prepared, on the day of the event the organizers asked Seybert to speak instead. In his 20-minute speech, he spoke about efforts that local police could take quickly to help find missing children and how the media could facilitate those efforts. A reporter from radio station KRLD approached the Dallas police chief shortly afterward with Seybert's ideas. This launched the Amber Alert.
