From the liner notes

After his girlfriend dumps him, softcore pornography screenwriter Carter Webb (Adam Brody) flees to Michigan to care for his ailing grandmother (Olympia Dukakis). There he begins work on a book he has always wanted to write but never could and becomes captivated by the family living across the street – a mother with two teenage daughters. He begins to find a connection with the neighbor, Sarah Hardwicke (Meg Ryan), as she battles with breast cancer. This building relationship, and the bond with the daughters, help Carter discover that life truly goes on.
