An innocent day at the amusement park turns into tragedy when Karla (Halle Berry ) watches as two strangers drag her six-year-old son, Frank (Sage Correa), into a car and drive away. Without a license plate number or mobile phone from which to call the police, Karla must find the little boy on her own. In a high-speed chase and with the fuel gauge dangerously close to reserve, Karla will have to make tough decisions if she wants to see her son again.
