Acid is a silent manifesto of the generation of twenty-year-old. They have been abandoned in a world adorned with concepts such as family, friendship, love, and opportunities. In search of answers to their questions, they devour themselves like a chemical substance that corrodes the world around, in order to eventually learn not to listen but to hear, not to look but to see. And to find their way. Sacha and Petya live the crazy life of young musicians in modern-day Moscow: loud parties, ups and downs, the wheel of unstable relationships with others and themselves. Knowing the importance of love, family, and opportunity, but feeling lonely and disconnected, has left them both with a sense that they are corroding from the inside. Suddenly an event occurs in their lives that requires them both to take an honest look at themselves.
