Baby's Day Out

Baby's Day Out is a movie starring Lara Flynn Boyle, Joe Mantegna, and Joe Pantoliano. After three kidnappers lose the baby they have kidnapped, both the cops and kidnappers go looking for the baby.
Baby Bink couldn't ask for more: he has adoring (if somewhat sickly-sweet) parents, lives in a huge mansion, and he's just about to appear in the social pages of the paper. Unfortunately, not everyone in the world is as nice as Baby Bink's parents—especially the three enterprising kidnappers who pretend to be photographers from the newspaper. Successfully kidnapping Baby Bink, they have a harder time keeping hold of the rascal, who not only keeps one step ahead of them, but seems to be more than a little bit smarter than the three bumbling criminals.
