Evgenia Selezneva, once a brilliant chemistry professor at a prestigious university in the capital, was forced to leave the bustling metropolis. The harsh twists of fate brought her to a quiet provincial town, where her former scientific career remained only a memory. Now her everyday life is filled with entirely different concerns: she works as an entertainer and special effects artist at a local escape room, trying to adapt to her new reality. One day, during another session involving a chemistry experiment, an irreparable tragedy occurs—one of the quest participants dies. The cause is a poisonous substance unexpectedly released during the experiment. Investigator Viktor Keller, who takes on the case, begins to examine the circumstances closely. Suspicion gradually gathers around Evgenia. The woman faces an extremely difficult task: she must not only uncover the true reasons behind what happened, but also find a way to prove her innocence.
