On December 23, the holiday season is in full force and the destinies of strangers intertwine: a hardened bachelor wants to find love; a couple expect their first child; a singer returns to the stage after a break; a mother tries to organize the perfect Christmas; a teen carries a big secret; a man struggles with the modern world; and the new manager of a large hotel must prove her worth.

Boys' college in eastern Quebec at the end of the 1940s. Brother Jean is not a teacher like the others. He wants to interest his students in the subject and to achieve this, he conducts archaeological excavations with his students aimed at proving the establishment of a Viking colony (Vinland) on the coast of the Saint Lawrence. The superiors of his congregation do not appreciate his unconventional ways of teaching. Without knowing it, Brother Jean will have a significant impact on the lives of his students, particularly in that of Émile, a young man who is having difficulty at school and who would prefer to abandon his studies to go work in a factory.
