Brussels, We're... Burning !

In Brussels, three students summon Satan to become rich, loved, and respected.
Bad news: he answers.
Very bad news: he sends a touchy demon and a hellfire that doesn't burn walls... but egos.
In an ordinary apartment tower, Guillaume a trainee firefighter nicknamed "Little Matchbox" tries to contain the blaze while his lieutenant calmly finishes his fast food. The building's caretaker guards his tower like a sacred relic, a brilliant lawyer refuses to be "ordinary," and a fallen Belzebuth discovers that even his own fire no longer obeys him.
The result: flaming shoes, collective hallucinations, existential breakdowns, and a demon losing his horns in public.
To survive, they'll have to stop trying to shine... and learn to stand together.
Because this kind of fire can't be put out with an extinguisher.
It's extinguished with humility.
