A wallet lost and found opens the door – just a crack – to romantic adventure for Georges and Marguerite. After examining the ID papers of its owner, it is not a simple matter for Georges to turn in the red wallet he found to the police. Nor is it that Marguerite can recuperate her wallet without being piqued with curiosity about whom it was who found it. As they navigate the social protocols of giving and acknowledging thanks, turbulence enters their otherwise quotidian lives. The new film by Alain Resnais, «Wild Grass», is based on the novel L’incident by Christian Gailly.
