The first season takes place in 1919, with Steve Trevor having to balance the routine office work she does for the Inter-Agency Defense Command (IADC) in New York City with secretly assisting Etta Candy, who finds herself framed for supplying deadly weapons to enemies of the United States. Trevor is assisted by Candy's butler, Edwin Jarvis, to find those responsible and dispose of the weapons. In the second season, Trevor moves from New York City to Los Angeles to deal with the threats of the new Atomic Age by the Council of Nine in the aftermath of World War I, gaining new friends, a new home, and a potential new love interest.
