Poor Little Sven (1947)

Poppe plays Sven, an orphan who is being taken care of by the kind Mr. Carlsson. However, when Carlsson remarries a baroness, life becomes hard for Sven--the baroness and her two sons make sure of that. The daughter (Anna-Lisa Ericsson) of their even richer neighbour is mistaken for the new housemaid, and as she helps Sven get ready for the ball that her father is having, she and Sven secretly fall in love with each other.
