Sally Field plays the titular role of sixty-something-year-old Staten Island shut-in Doris, an aging holdover in her Manhattan-based company who ends up developing a crush on a friendly, hunky, and much younger new employee named John Fremont.  Most of her interactions with John are in her own mind, but after she ends up partaking in a course with a motivational speaker, she decides to turn what she thinks is 'impossible' into "I'm possible!" and begins to try to make things happen by putting herself in the same social circles as John and his hipster friends.  John takes a liking to Doris, but is he just being friendly, or is he signaling that there could be something more between them?
