When Charlotte Robinette receives a phone call from kidnappers demanding a ransom for her daughter Kristen, her daughter's voice on the phone convinces her that the situation is dire. Over the next four grueling days, the kidnappers wear Charlotte down, keeping her on the phone, sending her all over Phoenix and having her wire money to Mexico. Finally, she's instructed to travel with the remaining cash to a small town across the border, where she's told she can rescue her daughter. Little does she know, a stop by the U.S. Border Patrol may end up being a lifesaver.
