The Informant

S1 E1: Inmate predators force weaker inmates to hide drugs in their cells and take the rap if they're caught. But one inmate risks his life and turns informant to help Sergeant Valerie "Snoop Dogg" Hampton and Special Agent John Fisher eliminate the inmates' outside drug source. Acting on this intelligence, the Squad conducts a massive cell search and ramps up their investigation outside the prison--where they hope to ensnare their suspect in an elaborate trap.
