When the evil wizard Gargamel chases the tiny blue Smurfs out of their village, they tumble from their magical world into New York City.
The Smurfs team up with their human friends to rescue Smurfette, who has been abducted by Gargamel since she knows a secret spell that can turn the evil sorcerer's newest creation - creatures called the Naughties - into real Smurfs.
