Omar, an unstable and lonely teenager, lives in a slum in the suburbs of Mostaganem, Algeria. He is addicted to a famous psychotropic, nicknamed “Madame Courage”: Artane tablets, very popular among young Algerians, for their euphoric effect of invincibility. Omar is an expert thief. One morning, he goes downtown to commit his usual crimes. His first prey is a young girl called Selma, walking with her friends, prominently wearing a gold necklace. As he commits his larceny, their eyes meet.
