Guillermo Guiz, whose real name is Guy André Daniel Michel Verstraeten, 34, is a stand-up comedian. The young man embodies the revival of Belgian comedy - contrasting with the more traditional generation of Taloche and Marc Herman - and imports a form of corrosive humor from the United States, tackling without taboo all subjects such as sexuality, racism or disability. Guillermo Guiz is on the rise: he goes from confidential clubs to bigger and bigger venues. This documentary is an opportunity to capture its rise to power.
