The Horn

Tom Sawyer and his best buddy Huck Finn love going fishing, daydreaming about pirates and stolen gold, and thinking about Becky Thatcher - the pretty new girl at school. But when these pals set out on a quest for buried treasure, they end up face to face with the town's most "grizzly" bear, Injurin' Joe. Giving Joe the slip, they find themselves in the middle of a fantastic adventure that takes them from the mighty Mississippi to the mysterious caverns of a secret hideout where they discover fun, excitement... and a fortune beyond their wildest dreams!

Because of a bet, Werner and his friend have to construct the fastest vehicle to win a race, because life depends on it.
