One day Bridget finds the perfect napping spot-far from Lulu-in a dark theater. But when the movie starts, Bridget hears a familiar voice singing along. It's Lulu howling! Bridget escapes the angry crowd, leaving Lulu trapped inside. Just when it looks as though Lulu will get her just deserts and Bridget will get some peace, Bridget decides to face the music on her friend's behalf-again. The love-hate relationship between Lulu and the naïve but goodhearted Bridget will resonate with pet owners, siblings, and friends.
