For a nanny, Sloan doesn't seem to really know his way around one child, let alone three. The truth of the matter is, Sloan's an undercover agent trying to break up an art theft ring, and the only way he can do it is to investigate while in disguise. When Jo, a business mastermind and rather plain aunt to the kids, decides to help out, Sloan may have just found the love of his life...or the target of the criminal case!
