Get ready for a high-speed countryside adventure! Charles and Lizzie Peterson are taking a break from their busy neighborhood to visit their cousins out in the country. But a relaxing vacation quickly turns into a new rescue mission when a beautiful, energetic border collie is suddenly abandoned right at their feet! They name the lively dog Flash, and he certainly lives up to his name. This intelligent pup has a powerful instinct to run, herd, and chase absolutely everything that moves. While Flash is an amazing dog, Charles and Lizzie quickly realize that his boundless energy means he cannot just live in an ordinary house or an apartment. He needs wide-open spaces, a job to do, and a family that can keep up with his active lifestyle. Finding the right match for such a spirited dog is going to be a huge challenge. Can the Petersons track down the ultimate forever home where Flash can truly run free?
