Johnny is a veteran member of The Lost, a notorious biker gang. Johnny has been creating business opportunities for The Lost in Liberty City, but his first loyalty must be to the patch he wears on his back and to Billy Grey, the club's President. However, when Billy returns from rehab hell-bent on bloodshed and debauchery, Johnny finds himself in the middle of a vicious turf war with rival gangs for control of a city torn apart by violence and corruption. Can the brotherhood survive?
