Looking to net a cool million by pinching some biological research vials from a lab, Adam McMullen (Matthew Broderick) recruits his grandfather, Jessie (Sean Connery) -- an unabashed lifelong criminal -- to help with the high-stakes heist. Meanwhile, Adam's father (Dustin Hoffman), once a chip off the old block, wants no part of the scheme but soon finds himself pulled back into Jessie's world to keep an eye on Adam in this comic caper.
