Zwei Wochen Chef (2007)

When her store is to be closed, a sales assistant wants to give "those up there" a real piece of her mind. On the management floor, however, Sara is mistaken for a new colleague who is supposed to get the fashion company back on its feet. She soon realizes that someone is literally cheating on the labels and turning the cheapest thread into supposedly high-end goods. Together with a dapper colleague on the board, she searches for the fraudster, but then she herself is exposed.
