Federal authorities thought they were about to shut down the American activities of the lethal MS-13 gang for good.

But when the star witness and the prosecuting attorney are murdered, the trial of the gang's leaders is in shambles. With legal avenues exhausted and an undercover agent missing deep within the deadly organization, the situation is critical.

Mack Bolan is called in to fight fire with fire.

But MS-13's leaders have a plan to terrorize suburban America. In order to stop them, Bolan will have to follow their trail deep into the Salvadoran jungle, moving fast and striking hard. Using warrior skills honed in another distant land, the Executioner will show no mercy.
