"The Confirmation" begins with 8-year-old Anthony (Lieberher) and his estranged father (Owen) spending two days together for the first time in forever, as the boy's mom (Bello) and new husband (Modine) head off to a religious retreat. Their mutual unease is exacerbated when the father's truck breaks down, his landlord locks him out of his house, and the toolbox that provides his living gets stolen. As they search for the stolen tools with help from an odd neighbor (Oswalt), the father and son begin to establish a connection.
