"From the moment you are born, you start to die."
"The Earth is 4.6 billion years old. You'll live to be a maximum of one hundred. Life isn't worth the bother "
So says Pierre Anthon when he decides that there is no meaning to life, leaves the classroom, climbs a plum tree, and stays there. His friends and classmates cannot get him to come down, not even by pelting him with rocks. So to prove to him that there "is" a meaning to life, they set out to build a heap of meaning in an abandoned sawmill.
But it soon becomes obvious that each person cannot give up what is most meaningful, so they begin to decide for one another what the others must give up. The pile is started with a lifetime's collection of Dungeons & Dragons books, a fishing rod, a pair of green sandals, a pet hamster--but then, as each demand becomes more extreme, things start taking a very morbid twist, and the kids become ever more desperate to get Pierre Anthon down. And what if, after all these sacrifices, the pile is not meaningful enough?
