What happened on that autumn Saturday evening?

Mia was dining at a restaurant when terrorist bloodbath took place in Paris. It’s been 3 months, yet Mia’s memories of that night were fragmented, and she is still too traumatised to live a normal life. To regain momentum to live, she revisits the scene and tries to reconstruct her memories. Could the finger pointing and denial of others bring happiness to Mia and help her get back on track?
