Three brothers, Snitch, Snatch and Sketch, are tired of foraging for scraps of food in the subway where they live. It’s not easy being a rat. One night, they go on an adventure through the city so that they will never go hungry again. After arriving at a house belonging to the Bumpkin family, they discover that a birthday party is taking place the next day for ten-year-old Horatio. The brothers hatch a clever plot to join the festivities and get the maximum amount of food – without getting caught. But one greedy brother spoils things with a plan of his own.
