At a Montreal railway station, passengers are stranded because of a snowstorm. One of the stranded, Pierre-Paul, discovers a young schoolgirl on the brink of suicide. While he searches for someone to intervene, Chili, the young girl, disappears, only to reappear of her own accord after Pierre-Paul's fruitless search. This brief encounter leads to flashback revelations and interaction among the supporting characters also stranded in the storm.
