After five years of studying in Paris, Arash is fed up with France. Haunted by feelings of unhappiness and despair, the sensitive Iranian student firmly believes that the French are a breed of their own. His friends Hossein and Ashkan persuade him to join them on one last trip, hoping to change his mind. The dissimilar trio hits the road, heading to the sun-kissed South of France with a jam-packed car. Sleeping on campsites, drinking beer at street festivals and frolicking in the fresh sea air they meet the two musicians Charlotte and Michèle and Arash is left to decide whether he really wants to return to Iran after all… BEFORE SUMMER ENDS presents itself as a documentary that continually seeks to play with the boundaries of fiction.
