Max is a dog who lives a happy life with his owner in a Manhattan apartment complex. Max has made friends with all of the pets in the building, and he even has friends in the building across the street. Max's owner disrupts life by bringing home the sloppy and inconsiderate dog, Duke. Max and Duke do not get along, but they have to put all of that behind them when they find out that an abandoned bunny pet is gathering all of the other pets together to take revenge on the pets with homes. Seems like kitty does a lot more than sleep when you are at work all day.
