When retired cat burglar Frank begins to show worsening signs of dementia, his harried big city son offers to provide him with live-in help: a highly qualified, perfectly polite butler who also happens to be a robot. Understandably, Frank resists at first (didn't you see The Terminator?), but he soon comes to see the advantages of his new mechanical buddy's skills... especially if they can help him get back in the heist game.
