 Federal Investigation Bureau ( FIB ) government agents Dave Norton and Steve Haines contact Michael and demand that he perform a series of operations with Franklin and Trevor to undermine a rival agency , the International Affairs Agency ( IAA ) . Under Haines ' direction , they attack an armoured convoy carrying funds intended for the IAA and raid a bank containing the payroll for all corrupt police and public officials in Los Santos . As Haines comes under increasing scrutiny for his methods , he forces Franklin and Michael to infiltrate the FIB headquarters and erase any evidence being used against him from their servers . Michael takes the opportunity to wipe any data on his own activities , destroying Haines ' leverage over him . The trio start planning their most daring feat ever : raiding the Union Depository 's gold bullion reserve .
