Leslie decides to put together a promotional calendar featuring the staff dressed as heroes of American history, with Ingrid on the cover as Betsy Ross. But Ingrid's display of ignorance about her character leads to the shocking revelation that she is actually an illegal alien from Poland. Jealous that Ingrid was chosen for the calendar cover instead of her, Amy decides to do something about the Greens & Grains' undocumented-worker problem. But Ingrid is not about to go silently, and the rest of the staff is not about to let Amy get the upper hand.
