The products at Shopwell's Grocery Store are made to believe a code that helps them live happy lives until it's time for them to leave the comfort of the supermarket and head for the great beyond. However, after a botched trip to the great beyond leaves one sausage named Frank and his companion Bun stranded, Frank goes to great lengths (pun intended) to return to his package and make another trip to the great beyond. But as Frank's journey takes him from one end of the supermarket to the other, Frank's quest to discover the truth about his existence as a sausage turns incredibly dark.
