Two years after prom night, three ex-couples look back on their last summer spent together.

From out of nowhere, the most beautiful girl in the world sits at the table across from me at the library. Is this a stroke of good luck or bad? Her smile paralyzes me… How will Sam win Nadine’s heart? Must he seek out his inner samurai to fight the monster of his anxiety? Real courage is conquering your fear.

During a harsh Montréal winter, an elementary-school class is left reeling after its teacher commits suicide. Bachir Lazhar, a charismatic Algerian immigrant, steps in as the substitute teacher for the classroom of traumatized children. All the while, he must keep his personal life tucked away: the fact that he is seeking political refuge in Québec – and that he, like the children, has suffered an appalling loss.

Neglected by his father, William, a star college hockey player, also suffered harassment from his coach and some teammates. By chance of a visit to Sainte-Justine hospital, the young man, whose morale and motivation are at its lowest, meets ten-year-old Daniel, awaiting a kidney transplant. Their passion for the Habs unites them instantly and William tries, by all means, to give him hope in the face of the disease.
