Gambling everything, including the family farm, Cayden McNamara travels to the 1893 Chicago World's Fair with his most recent invention. But the noise in the Fair’s Machinery Palace makes it impossible to communicate with potential buyers. In an act of desperation, he hires Della Wentworth, a teacher of the deaf, to tutor him in the art of lip-reading.

The young teacher is reluctant to participate, and Cayden has trouble keeping his mind on his lessons while intently watching her lips. Like the newly invented Ferris Wheel, he is caught in a whirl between his girl back home, his dreams as an inventor and his unexpected attraction to his new tutor. Can he keep his feet on the ground or will he be carried away?
