Lucy is a curious chocolate labrador retriever who lives at a house on the lake with her family. She loves to explore all the fun down at the lake, like swimming with the fish, chasing blue herons, feeling the wind as the sailboats race by, and watching the clouds make funny shapes. If she had her way, she would run around free at her leisure every day, but one summer morning when her patience is tested, she realizes all of life's sweetest moments are best spent with the ones she loves.
