His daily life is turned upside down by the arrival of a new neighbor, Élyane Boisjoly (Sarah-Jeanne Labrosse), a famous instagrammer for whom he develops a fascination. His life is turned upside down when one night his obsession with Élyane disturbs him to the point of making him miss a delivery. In a violent manhunt orchestrated by Dom, Jeremy has no choice but to act.
