When her probationary employment ends without her being hired, Rosetta (Émilie Dequenne) engages in a violent struggle against her manager and the policemen when she refuses to leave the premises. She returns home to "The Grand Canyon", the caravan park where she lives with her alcoholic mother, who mends worn clothes for Rosetta to sell to charity shops. They get into a physical struggle over her mother accepting gifts from men for sexual favours. Rosetta goes to a nearby river and lays out fish traps to poach trout for food. Unable to receive unemployment pay, refusing to take welfare and desperate for work, Rosetta asks around for vacancies until she comes upon a waffle stand. She befriends the worker, Riquet (Fabrizio Rongione) and asks the owner (Olivier Gourmet) for a job, without success. Later, Rosetta treats her period cramps with pain relievers and a hairdryer warming her abdomen.
