A young homeless actor wanders in Paris and tries to find the way in his life through unexpected meetings, which will challenge and change his vision of humanity.

Alexander, a young actor, has been falling for a few months in a spiral of self-destruction, becoming strongly addicted to alcohol and drugs. One night, he is stabbed by drug dealers and almost dies. To get out of his addictions he wrote the scenario of a film "Spiral" close to autofiction where he would play the main role of Daniel. Olivier Rainer, a director whom he admires, agrees to direct the movie and make Alexander pass screen tests while rewriting the script by incorporating elements of the personal life of the actor. Alexander wishing to exorcise his demons and reach his catharsis will follow Olivier unconditionally in a blistering adventure where reality and fiction merge.
