Mik Murdoch has swallowed the magical berry from the guardian of the Cave of Wonders and with it he's realized his dream to acquire superpowers. He's also realized what you wish for and what you get are often two different things. While Mik has superpowers, he's having a really hard time with control. In fact, he's starting to wonder whether being a boy superhero is a good thing or not.
What's worse, his weird behaviour doesn't go unnoticed by his parents, who decide to take him away to the lake for the summer, assuming he needs time to unwind and relax. It's there Mik uncovers the truth behind an ancient mystery and learns that letting others help doesn't make him weak.
