The slang word "Psevdezh" is a free translation of the philosophical term "simulacrum" and means a sign that does not have a signified object in reality. The heroes of the film are trying to understand whether the activity of others is this very pseudo-death. A team of young actors begins to work on a performance that is dedicated to conceptual artists, heroes of the 90s. In the course of work, the two creative groups constantly collide, and with each meeting, both in actors and in artists, mutual irritation will grow.
