You will play as gangsta which is living in LV, away from his native town: LS. Going home on the highway the car start to produce fire from the engine and you need to get out from there. Remaining with no ride some friend of your brother give you a lift to his club where you told what was happen and that you need a place where can lay low. He know just the place: a house near Emmet where the owner is a pervert old man. After his "accidental" dead, the new owner will be you.
