When Miss Beatrix Waterbury's Chicago-bound train ride is interrupted by a heist, Mr. Norman Nesbit, a man of science who believes his research was the target of the heist, comes to her aid. Despite the fact that they immediately butt heads, they join forces to make a quick escape.

Upon her arrival in Chicago, Beatrix is surprised to discover her supposedly querulous Aunt Gladys shares her own suffragette passions. Encouraged by Gladys to leave her sheltered world, Beatrix begins working as a salesclerk at the Marshall Field and Company department store. When she again encounters Norman on a shopping expedition, he is quickly swept up in the havoc she always seems to attract.

But when another attempt is made to part Norman from his research papers, and it becomes clear Beatrix's safety is also at risk, they soon discover the curious way feelings can grow between two very different people in the midst of chaos.
