Summary
In the height of the Roaring Twenties, a modest man finds himself the target of a psychological and financial experiment that would make modern influencers shudder. 600000 francs par mois follows the frantic journey of a protagonist tasked with a seemingly impossible challenge: he must spend a staggering 600,000 francs every single month. This isn't a simple shopping spree; there are strict stipulations against investment, charity, or accumulation. The film reinterprets the 'inheritance with a catch' trope, transforming a dream of luxury into a grueling, high-stakes marathon of consumption. As our hero navigates the elite social circles of France, the story shifts from a lighthearted romp into a sharp observation on the absurdity of capital. The wealth that should have liberated him becomes a cage, forcing him to confront the hollow nature of excess while trying to maintain his sanity and his social standing. It is a race against the calendar where the finish line is a zero-balance bank statement, proving that in the world of the ultra-rich, the hardest thing to do is actually lose money.
