In the near future, Frank (Frank Langella) is a retired catburglar living alone, while his successful son, Hunter (James Marsden), tries to care for him from afar. Finally, Hunter gets him a robot caretaker (voiced by Peter Sarsgaard), and Frank soon learns that the robot is useful as a burglary aide. As Frank tries to restart his old profession, the uncomfortable realities of a changing world and his worsening dementia threaten to go beyond what any robot can do for him.
