Max Dugan (Jason Robards Jr.) is an elderly ne'er-do-well whose tenuous mob connections have made him persona non grata with his daughter Marsha Mason. Struggling to raise her restless son Matthew Broderick on her own, Mason is none too pleased when Max returns to the family fold with yet another portfolio of get-rich-quick schemes. Forced to leave town due to the investigative habits of cop Donald Sutherland, Mason's new boyfriend, Max does one last good deed to renew the faith of the disillusioned-with-life Broderick. Watch for Donald Sutherland's son Kiefer in his film debut, and for former Kansas City Royals' batting coach Charlie Lau in the baseball-game finale.
