The film has two alternate endings, which are shown consecutively. In the first, Julien and Sophie decide as an ultimate dare to finally share their dream together, their "dream of an eternal love" – the pair embrace while they stand in a construction pit that is about to be filled with concrete. The couple kiss as they are pulled beneath the cement, and both drown in the sludge. The other ending has the now aged Julien and Sophie spending time together in a garden and carrying on playing their game with milder dares. However, the opening scene of the film (an overhead view of a building site and a pit filled with concrete in which the upper side Julien's tin box rests partially sunk) replays, suggesting that the two friends actually did bury themselves and drown beneath the concrete.
