When Gustavo goes away for a few days to check out a new boyband called "The Windmills", the guys "mansion sit" for him much to Gustavo's dismay. After much discussion with Kelly, Gustavo allows the boys to "mansion sit" but they must follow his rules or else they are fired. Once at the mansion the guys think it will be an easy task, but what seems like a task they can handle soon turns into a "big time disaster" as things don't go according to plan. Meanwhile with Kendall and the guys away, Mrs Knight starts to fell less needed by her children, so Katie decides to help her mother out by pretending to be sick.
