The testosterone fueled world of fast cars and heavy machinery may not be the typical place for a woman, but that hasn't stopped Jacqueline, AKA Jack, from becoming the best mechanic in the machine shop where she works. When an ailing race car needs to be fixed immediately, Jack's boss pits her against her two sexist male co-workers to come up with the solution, or risk losing their jobs. Jack must endure ridicule, misogyny, and even harassment in order to keep her job and prove that this male-dominated world just might need a woman's touch.
