"The film is the story of an undercover agent who, after failing to protect an important government scientist, learns the man's family is in danger. In an effort to redeem himself, he agrees to take care of the man's children only to discover that child care is his toughest mission yet."

I've seen this movie several times; and was sure I had reviewed it before; but I couldn't find any sign of a review for it in my old posts (unless I missed it somehow), so I'm reviewing it now. Anyway, I think it's an absolutely fantastic movie!
