Hank Ketcham's beloved comic strip comes to life again in this film sequel. Wherever Dennis (Justin Cooper - "Liar, Liar") goes, mayhem follows--and it always seems to land in the lap of his long-suffering neighbor, Mr. Wilson (Don Rickles). This time, with the help of high-spirited Grandpa, Dennis helps foil two con men from swindling Mr. Wilson with a fountain-of-youth scam. No one can predict what this little boy with the insatiable curiosity, inexhaustible energy and unstoppable good humor will do next. Co-starring Emmy-winner Betty White ("The Golden Girls") and Oscar-winner George Kennedy ("Cool Hand Luke").
