Amber Alert can best be described as every parent’s worst nightmare come true. The premise has a ride-share driver and his passenger following a Toyota Camry after receiving a child abduction notice on their phones. The film’s taut and harrowing first act will keep you glued to the screen despite obvious logistical flaws. That tension is then wasted as the primary characters engage in poorly written exposition meant to develop the protagonists’ relationship. Thankfully, Amber Alert gets back on track for a violent climax that has its problems but recaptures the riveting earlier anxiety.
