Tom Swift has finished his latest invention: the Red Cloud, a fast and innovative airship and Tom is anxious for a cross-country trial. But just before he and his friends take off, the Shopton bank is robbed. No sooner is Tom in the air than he blamed for the robbery without his knowledge. Suddenly, he's a wanted fugitive, and doesn't know why until he's half-way across the country. With no safe harbor or friend on the land below, Tom must race back to Shopton to clear his name before he's shot out of the sky. (source: Wikipedia)
