Introduction：Set in the summer of 1986, Franklin Saint  and his entire family are rich beyond their wildest dreams, on the verge of having everything they've ever wanted... right as the ground begins to fall out from under their feet. The sudden and tragic death of basketball star Len Bias makes the rock cocaine epidemic front-page news, the target of both Democrat and Republican lawmakers. Law enforcement is on a warpath and the militarization of the L.A.P.D. continues as police and politicians decide the only way to deal with this growing scourge is through force - and the creation of the new C.R.A.S.H. (Community Resources Against Street Hoodlums) units. The streets of South Central Los Angeles have never been so dangerous as the Saint family navigates the police, the warring gangs and the CIA.
