Family comedy sequel featuring a blend of CGI animation and live action based on the iconic characters created by Peyo for the 1980s television series. When the dastardly Gargamel (Hank Azaria) kidnaps Smurfette (voice of Katy Perry) and steals her away to Paris, the rest of the Smurf gang team up with their human friends Patrick (Neil Patrick Harris) and Grace (Jayma Mays) to try and rescue Smurfette from Gargamel's evil clutches. However, with Smurfette the key to Gargamel's plans to transform his latest minions, the Naughties (voiced by Christina Ricci and J.B. Smoove), into Smurfs, this will be no simple task - not least because Smurfette seems rather taken by the Naughties...
