Molly is a young golden retriever dog who loves going for car rides with her human. However, when her human stops for a red light one sunny afternoon she reunites with her brother, who was named max, that she hasn't seen since they were young puppies. Max is very excited to see Molly and starts to climb out the window of the car to get closer to greet his sister. Molly has to think quickly to convince Max to stay in his car. Max agrees after a lot of convincing and Molly agreeing to try to meet at that set of lights later that day.
Once the two dogs meet up they talk for hours and discover that Max now lives a few blocks away. The two dogs decide to get their humans to meet and become friends so that the two dogs can visit more often.
