In early November 1941, Annie Fox is an Army nurse in the Philippines when she’s transferred to Hickam Field in Honolulu. Between the bombers at Hickam and the battleships next door at Pearl Harbor, Hawaii is an offensive powerhouse for the United States and, thus, a big target for its enemies. Annie’s on her way to work when the first Japanese Zero fighter plane flies over Hickam’s Parade Ground. The death and destruction that follow leave her no time to process what’s happening. What follows is an intense day, filled with unexpected alliances and undo hardships – especially when one of Annie’s friends and fellow nurses, who is Japanese American, is arrested under suspicion of being a subversive, putting Annie’s love for her country to the test.
