When the lights are turned off and all the people leave, a grocery store magically transforms into a city: the boxes become buildings, the aisles turn into streets. The Chinese food aisle becomes China Town, the Italian food aisle becoming Venice, and so on. Then out from every door of this 'marketropolis' come two types of characters: ones you already know -- some of the most famous characters in the world, like Mr. Clean, Charlie the Tuna, the Energizer Bunny and more; and ones you are going to meet, and the actual stars of the movie.
These include Dex Dogtective (Charlie Sheen), the super sleuth and head of the USDA (United Supermarket Defense Association); Daredevil Dan (Wayne Brady), the world's worst flying squirrel stuntman; the sweet and lovable Sunshine Goodness (Hilary Duff); and the villainess and seductive Lady X (Eva Longoria). They all hang out at the Copa-Banana, the hottest nightclub in town (in the produce section). However, all's well until Brand X moves into town and Lady X and her minions try to take over.
The only way to stop them is...yes...A FOODFIGHT!
