One day, he was sent by his boss to a military base in Honolulu, Hawaii, where a spy satellite was being developed and needed Brian's supervision. Brian set out on a journey in high spirits. To Brian's surprise, at his destination, waiting for him to work with him, was a female pilot named Alison (Emma Stone Emma Stone). Alison was cold and unsmiling, and she was really a serious and boring woman, which made Brian feel very depressed, at the same time. Brian still has unrealistic illusions about his ex-girlfriend Tracy (Rachel McAdams Rachel McAdams). He contacts Trish and tries to get back together with her.
