The five Wright cousins have a submarine and they know how to use it! But the deeper they dive in the waters of Lake Pinecone, the more mysterious the lake becomes. It contains many hidden and unexpected secrets! To top it off, something spooky is wrecking boats on the lake and it's downright scary.
