Film Synopsis

At the start of the 19th century, a young officer recently promoted to a small garrison takes lodgings with a bourgeois family who are as dull as they are quiet.  One evening, there is a new face at the dinner table, Albertine, his landlord's daughter.  At first, the attractive young woman appears indifferent to the officer, but she soon begins to make subtle gestures to show that she is attracted to him.  They become lovers, although Albertine's parents suspect nothing, as she keeps up the pretence that she has no interest in the officer when she is in their sight...
