Max is a battle-weary veteran of the wedding-planning racket. His latest — and last — gig is a hell of a fête, involving stuffy period costumes for the caterers, a vain, hyper- sensitive singer who thinks he’s a Gallic James Brown, and a morose, micromanaging groom determined to make Max’s night as miserable as possible. But what makes the affair too bitter to endure is that Max’s colleague and ostensible girlfriend, Joisette, seems to have written him off, coolly going about her professional duties while openly flirting with a much younger server. It’s going to be a very long night… especially once the groom’s aerial serenade gets underway.

Arnaud, facing an uncertain future and a dearth of choices in a small French coastal town, meets and falls for the apocalyptic-minded Madeleine, who joins an army boot camp to learn military and survival skills to prepare for the upcoming environmental collapse. Intrigued and excited by Madeleine’s wild ideas, Arnaud signs up for the boot camp himself. They soon realize that the boot camp is harder than they’d imagined, but the experience nonetheless cements them together as the couple continues to explore their young love.
