Doppelganger

Propelled out of his safe, ordinary world, Andrew is caught in the midst of a desolate city, torn apart by vicious gang wars. Here, the rules of survival are simple—you follow the pack, or you die. Dragged into one gang's brutal takeover campaign, Andrew has no choice but to embark on an unthinkable mission, in an attempt to sever the connection between the two worlds forever. If he succeeds, he will destroy everything in his life. But if he fails, hundreds will die—in both worlds.
