The Third Street Saints have only ever known one leader since the murder of Julius—The Boss. The Boss gripped their small town gang by the throat and fucked it until they knew their place, above all other gangs in Stillwater. The Saints rose to the top and begin to branch out, with the help of his closest lieutenants, Johnny Gat, Pierce Washington and Shaundi. The Boss, however has a secret. The gang isn’t solely run by him. It’s also run by his little sister. The one with the brains, as she likes to call it. She runs the heists, the logistics, the money, the schemes. He enacts it out as her brawn. They made a promise long ago to never expose her, so she couldn’t become a target. Until today. A mission gone wrong and STAG on their asses as they expand into Steelport as her exposing herself to save Johnny Gat. Now, The Boss desperately tries to keep his secret while two bosses, a pair of sociopathic twins run the gang. What could possibly go wrong?
