Max, a seasoned veteran in the wedding planning industry, is tackling his final event, which promises to be a chaotic extravaganza. The celebration features caterers dressed in elaborate period costumes, a self-absorbed singer who fancies himself the French James Brown, and a gloomy groom who insists on micromanaging every detail, making Max’s job a nightmare. Adding to the turmoil, Max’s colleague and supposed girlfriend, Joisette, appears to have distanced herself, focusing on her work while openly flirting with a much younger staff member. The night is set to be interminable, especially when the groom’s aerial serenade begins.
