Four Boys from 1908 are accidentally hurled into the modern world when they accidentally use a secret time machine. While they attempt to build a machine that will send them back to their own era, they struggle to "fit in" in the future - in their own home town - that is wildly different from 1908. While in the future, they stay with the great grandson of one of the brothers: a long-haired, retired, "hippy" rock-n-roller. They teach their new friends how to defend themselves against the school bullies.
Ultimately, they enter a "Battle of the Bands" in hopes of winning the money they need to secretly buy parts for a time machine. But...can they play? Lots of action, comedy, and a world-class soundtrack.
