The story follows single mother Laura (Farmiga) who, along with her awkward 14-year-old son Henry (MacDougall), is forced to drive her estranged, care-free, pot-dealing father Jack (Plummer) across country after he's kicked out of yet another nursing home. The road trip veers off course when Jack decides to make a couple of stops and Henry asks to see his deadbeat dad Leonard (Cannavale).
