<P> In the fictional town of Oakton City, a purple squirrel named Surly (Will Arnett) and his mute rat partner Buddy reside in Liberty Park where their thieving reputation has made them outcasts . A group of urban animals led by Raccoon (Liam Neeson) and his cardinal assistant are running low on food for winter . Red squirrel Andie (Katherine Heigl) and glory hogging gray squirrel Grayson (Brendan Fraser) compete with Surly and Buddy to scavenge from a peanut cart manned by Lucky (Scott Yaphe) and Fingers (James Rankin) who are casing a bank . The squirrels' efforts inadvertently end with the cart's propane tank exploding in the park after its cord was bitten by Fingers' pug Precious (Maya Rudolph). The runaway cart ends up destroying and burning the tree, where the animals store their food . Surly is banished and Buddy follows him . </P> <P> In the city, they find Maury's Nut Shop . Adjacent to the bank, it is a criminal hideout used by Lucky, Fingers, their boss Percy "King" Dimpleweed (Stephen Lang) and Knuckles, who plan to break through the wall and replace the bank's cash with nuts . King's girlfriend Lana (Sarah Gadon) believes King has gone straight and the nut store is legitimate . </P> <P> Raccoon sends Andie and Grayson to the city to find food, but they get separated when a street rat approaches them . Andie recovers Fingers' dog whistle, which Knuckles threw out and Surly had used against Precious, and threatens to dispose of it if Surly does not share the nuts he is going to take . Surly accepts and unwittingly befriends Precious after threatening her with the whistle . Andie informs the park community of the plan . Raccoon reluctantly goes with the plan and assigns Mole (Jeff Dunham) and the Bruisers to go with her . Surly eventually learns from Mole that Raccoon's policy is to control the food supply in order to control the animals, and that Raccoon plans on sabotaging the nut bonanza . When Andie does not believe him, Surly leaves after Grayson reunites with them . </P> <P> After fending off street rats who work for Raccoon, Surly and Grayson chase the criminal gang's getaway truck, which carries Raccoon and the other animals . Surly fights off Cardinal, and Mole defects from Raccoon and reveals the truth to the animals, resulting in Raccoon being voted out of the park community . King and Knuckles use the dynamite inside the empty truck to blow up a police barricade at a dam, but the police shoots the tire on the truck that falls from the dam . It explodes after Surly gets himself and Andie off it, and they fall into the river below . Surly makes it to a log, but finds out that Raccoon, King and Knuckles survived the explosion . Raccoon tries to kill Surly, but the nuts' weight begins to break the log . The animals arrive to rescue them, but Surly, deciding to be selfless in order to protect his friends, lets go of the log and falls into the waterfall with Raccoon . The park community now sees the good side of Surly, and mourns him . </P>
