The house on Rue Plumet is an old, big house in which Valjean and Cosette lived with their housekeeper, Toussaint. This house was located in a deserted place, and was hidden by big, wild garden.
It was in the garden where Cosette had her secret meetings with Marius. In the musical, Marius climbs a fence to reach her, although it doesn't appear in the 2012 film. Valjean and Cosette fled to the house from Gorbeau House after finding out that Inspector Javert was still on their trail.
In the book, the house number of Rue Plumet is #55; in some musical productions it is #5.
- The word "Rue" in French simply means "a street".
