The movie has been set approximately ten years after the events of the original BioShock. Here in the movie the halls of Rapture again echo with sins of the past. It is seen that on the Atlantic coastline a monster snatches little girls and brings them back to the undersea city of Rapture.

In the game the players step into the boots of the iconic denizen of Rapture famously called the Big Daddy while traveling through the decrepit and the beautiful fallen city. They are on the way chasing an unseen enemy searching answers and also their own survival.
