In 2007, David Moran (William Atherton), a Wall Street player, witnesses a man hit and run by a car. He responds to the situation and tries to resuscitate the victim. That evening, he reflects on his past to the summer of 1958, when he meets his first teenage crush Meg Loughlin (Blythe Auffarth). Meg and her disabled sister Susan (Madeline Taylor) have lost their parents in a car accident and because of this, they are sent to live with their reclusive aunt, Ruth Chandler (Blanche Baker), and her sons, Willie, Ralphie, and Donny (Graham Patrick Martin, Austin Williams and Benjamin Ross Kaplan).
