Alexander, a young actor, fell for several months in a self-destructive spiral, becoming addicted to alcohol and drugs. One night, he was stabbed by traffickers and nearly died. To get out of his addictions, he wrote the screenplay for a film "Spiral" close to autofiction in which he would play the main role of Daniel. Olivier Rainer, a director he admires, agrees to direct the film and test Alexander while rewriting the script and incorporating elements of the actor's personal life into it. Alexander, who wishes to exorcise his demons and achieve his catharsis, will follow Olivier unconditionally on a dazzling adventure where reality and fiction merge.
