Guy leads a life as a cashier in a bank that is mainly characterized by the daily routine and the chaos and violence around him. Every day his bank is robbed anew, but Guy has resigned himself to this. One day, however, he finds out that he is actually living in a brutal open-world video game called "Free City" and is a so-called NPC - a video game character that is not controlled by a human player. The programmers Milly and Keys, who have hacked "Free City", are responsible for this realization. Guy falls in love with Milly's avatar Molotovgirl, but the fact that an NPC is behaving strangely does not go unnoticed by the minds behind the game. The publisher Antwan wants to shut down "Free City" and now it's up to Guy to save himself and the other video game characters.
