Finnegan Osler is a rather unusual 15 year old boy, wearing a weary pair of rainbow rain boots and a miner's-cap-like helmet everyday. Perhaps even more unusual; Finn does not speak. His truest happiness and solace lies in his three friends, "The Adventurers", as the group calls themselves, and with them, he's constantly on a new adventure. But when a shocking discovery is uncovered that drastically alter's Finn's life, this friend group must make the decision that their children's playtime title may become much more true than they had ever imagined.
