CIA super agent Bob Ho (Jackie Chan) has been dating Gillian (Amber Valletta) for three months. Her kids Farren (Madeline Carroll) and Ian (Will Shadley) hate him. Little Nora (Alina Foley) thinks that he's a cyborg. He is retiring for Gillian but she doesn't know his secret life. Glaze (George Lopez) is his handler and Colton James (Billy Ray Cyrus) is a fellow agent. His Russian nemesis Anton Poldark escapes from capture. While the kids snoop around in his house, Ian downloads a file from his secret computer. Poldark tracks it down and comes after Bob and the kids.
There is absolutely no chemistry between Jackie Chan and Amber Valletta. The kids have better chemistry with him. Maybe they could have made up a story about him being a secret nanny instead. That's where the comedy is anyways with him as Mr. Mom. The movie almost works with him and the kids. Many comedians have mined that rich vain and Jackie could easily do that too. Also I don't know why he has to wear those glasses. It's not like he's Superman and this is his secret identity. The rest of the movie is a bunch of unfunny cartoon characters. It still has Jackie Chan doing his acrobatic fights. That's impressive at his age. With a few changes, this could have been a passable kids movie.
