Lucy convinces Mr. Mooney that she's too ill to come to work so she can go to a department store sale.
After examining some of the items for sale in the store (and causing a lot of damage), she learns she is the 10-millionth customer and wins many valuable prizes.
One prize she wins isn't one to her liking - her photograph will appear prominently in the next day's morning newspaper. Lucy goes to great lengths to make sure that her boss doesn't see the incriminating photograph and fails miserably.
