Follow the family business of identical twin brothers, Mike and Geoff Howe, as they design and build the coolest machines you ve ever seen: from high-speed military tanks to supercharged subterranean rovers. In each episode the tumultuous twins will push the limits of innovation by building a new, ingenious, and often insane machine. Working with their loyal shop crew, the Howe brothers put everything they have into their inventions. No idea is "too crazy" or "too half-baked" to try, but the success or failure of each invention could make or break their small shop on the verge of huge success.
