Invaders - Season Finale

S16 E22: Murderous home invaders strike close to home -- The latest murder victims of two home invaders are the family members of a man who once sold fake DEA badges to the killers and then began secretly cooperating with police. The case takes a harrowing turn when one of the law enforcement teams is put in the line of fire. In a legal gambit, A.D.A. McCoy (Sam Waterston) must then risk his career -- and those of others, as well -- to bend the rules and use corrupt DEA Agent Almonte (guest star Ritchie Coster) to lure out the sadistic psychopaths. Dennis Farina, Jesse L. Martin, Annie Parisse, S. Epatha Merkerson and Fred Dalton Thompson also star.
