Otherworldly entrance is prohibited. Lander E.

In St. Petersburg, children disappear-without witnesses, without traces. No one can find them: neither the police, nor volunteers, nor. The institution of hypothetical history, which protects people from otherworldly forces.

The tenth grader Margo also disappears, and the girl starts to search for her. But he finds Vasily, a young restorer who was in trouble after a clash with creatures from another world. They understand that the oddities taking place in the city are related to each other.

Only employees of the institute can help understand. Feeling paranormal activity, they go to young people. And all together are drawn into the game of otherworldly, from which you can get out alive only under one condition-a rack of a ball of history.

What secrets does St. Petersburg hide?
