Every hero has a story. This one starts with a girl and a racing tractor. Sally Slick knows she's meant to be more than a Midwestern farm girl. What she wants more than anything is to be an inventor when she grows up and she has the custom-built racing tractor to prove it! But, when Sally's big brother comes back from Chicago with a robot in hand and mobsters on his heels, Sally, with wannabe hero Jet Black, will risk everything to protect the people she loves!
