April secretly arranges for her father Bill to meet face to face with his brother Henry, so they can attempt to reconcile after a petty childhood dispute caused them to stop speaking forty years ago. The effort may be for naught, however, when Bill eats a piece of cheesecake baked by Monroe, who did not realize it was an old Russian recipe for homemade poisoned rat bait.

In order to reduce the cost of a trip to Europe, Jackie and Sara swap apartments with an English couple who wants to visit America. Henry's misgivings are confirmed when he accidentally opens a piece of their luggage that contains a high powered rifle, and concludes they are on a mission to assassinate a Russian ambassador.
