"sometimes the scariest part is seeing other people scared." A school in France. The class is rehearsing a theatrical performance: there are words and geometry on the blackboard; Marty Lang recited a poem, notes came from the room, and Daniel's nose began to bleed. The daily events that occur in dreams are vague and illusory. Invisible lines determine the road. Ten-year-old Daniel suddenly found himself alone with Marty, who was wearing underwear and didn't notice him at first. The encounter was gentle, but lost and took place in a vacuum. At the same time, something evil is approaching from the outside-something without a name, and adults always warn them. It wants to go from windows and doors to the children.
