During a meeting of the Butterfly Club, Brad is daunted to realize just how far butterflies have to travel when they migrate. He really wishes there was something he could do to help protect them, but the job seems way too big for him. There's just one thing he can do... To the Secret Museum! Our heroes are sent back in time to meet someone else who cared deeply about protecting nature: Rachel Carson. Brad watches in amazement as Rachel first performs simple tasks to help protect the wetlands near her home, then works her way up to studying and helping to protect all of the amazing life found within the world's oceans. Rachel inspires Brad to figure out his own way to help the butterflies, even if he is only a kid because we can all help to protect the Earth.
