Brian (Bradley Cooper) is an arms contractor. At a young age, he has broken into his own world in the industry and climbed to the top of his career. One day, he was sent by his boss to the Honolulu military base in Hawaii, where a spy satellite development and research was being carried out, which required Brian's supervision. Brian embarked on the journey with great interest. What Brian didn't expect was that at the destination, waiting for him to work with him was a female pilot named Allison (Emma Stone). Allison was cold and unsmiling. She was really a serious and boring woman, which made Brian feel very depressed. At the same time, Brian still had unrealistic fantasies about his ex-girlfriend Tracy (Rachel McAdams). He contacted Tracy in an attempt to reunite with her.
