It's October 1986 in this sixth and final season, as civil war threatens to destroy the Saint family. Franklin is desperate, forced to rob his Aunt Louie and Uncle Jerome after being wiped out by former CIA officer Teddy McDonald. Meanwhile, Louie has taken over Franklin's role as Teddy's sole buyer, undercutting her nephew and creating a competing empire in the process. Franklin is now faced with losing everyone he loves and everything he's built, and coming through it all will mean out-maneuvering the KGB, the DEA and the CIA, as well as avoiding the LAPD's fully militarized, fully corrupt, C.R.A.S.H units. When everyone has their backs against the wall, who will they become in order to survive?
