The story of two men in different timelines who set out to defeat Louis, a ping pong player, at a ping pong table near an apartment.

Dávid - a man living alone - one day receives an email. The email is about an unknown but also special software that is offered only for him, for free. Dávid's friend Oszkár tells him that the software is capable of rewriting reality, but also warns him to ignore the email, because it can be dangerous. Dávid doesn't listen to Oszkár, and downloads the software.
