Ranger, the time-traveling golden retriever with search-and-rescue training, arrives in New Orleans as Hurricane Katrina approaches and residents start to evacuate the city. Ranger meets Clare Porter, who is searching for her grandmother. Once Ranger helps Clare find Nana, he takes shelter with them at their home in the Lower Ninth Ward, and they wait for Clare's father to return from the gas station. But there's no sign of him as hours pass and the weather gets worse. The wind picks up and rain pours down. And when the levees break, floodwaters dangerously rise, and Clare and Nana are separated. Can Ranger help Clare navigate the flooded streets to safety and back to her family?
