Sandra Mercier is twenty-three years old when she makes the deliberate decision to end her life. She lives with her flatmates Margot and Emma, hangs out with her boyfriend Matt, but no longer feels understood or enjoys the company of others, and can only find refuge in her imagination. For Sandra, every day is a struggle, a crusade to seek bliss, an endless battle to choose life and to fight off the dark thoughts that consume her. Eventually, she becomes trapped in her mental realm, the very one she created to escape her reality. The hope for a better tomorrow that never comes, and the realization that her life did not turn out the way she expected, make Sandra believe she will find happiness in death... Until she has an encounter that changes her life.
