Marie, in her forties, has been carrying out the same daily routine at her gas station ever since she lost her son. She secretly awaits his return, although he died some years ago. Then Antoine, a young man who's a little adrift, enters her life. She's quick to take this twenty-year-old under her wing as though he were her own son. But, unbeknownst to Marie, Antoine has a whole other agenda. She mothers him until he commits a fatal act. An act that will change their lives forever.
