19-year-old Fiona Caufield is home from college for the summer and finds out that her handsome neighbor, Jasper, whom she's had a crush on since she was 11, is now divorced.
Although he's 20 years older, she thinks he's a living dream and decides to give him her innocence as a perfect way to cheer him up and “bring him back to life” after his horrible divorce.
But what Fiona thinks is just a sexy summer fling is something much bigger for Jasper, who has no intention of letting his perfect 19-year old lover return to college in Boston.
He's got a plan to make sure she stays in New York and becomes his wife, he just doesn't let Fiona in on his secret until the last moment— and by then it's too late.
