When the Proud Family goes Christmas shopping, they find a homeless family. While Oscar is reluctant and greedy, Penny invites the family to Christmas dinner. Once Christmas ends, Oscar is surprised to find them arrive the next day, where they teach the Prouds about Kwanzaa. But, the homeless family is not what they seem, as the Prouds will soon learn.
At a barbecue, Oscar nearly burns the Boulevardez's house down, and the Prouds take their neighbors in while they await repairs, much to the chagrin of Penny who is forced to share her bedroom with LaCienega. But when an embarrassing Boulevardez family trait is revealed during swimming class, Penny finds that the idea of her rival being knocked down off her high horse isn't as enjoyable as she thought it would be.
