Ruth Duffy (Rachel Keller) is getting by on an assistant's salary at a pricey school for girls in Manhattan, managing to move beyond the trouble and loss of her teenage years. Jonny Collins (Finn Wittrock) is working local jobs and living the life of a wily thief near the Throgs Neck Bridge in the Bronx. When they cross paths after years apart, Jonny is as consumed with Ruth as he was in high school, and infiltrates her life with the unwitting involvement of Nan and Steven Noble (Emily Mortimer and James Ransone).
