Set amid arrests and subsequent trials surrounding the 2008 Republican National Convention, this portrait of two young activists caught in the web of an opportunistic mentor and a desperate justice system poignantly describes both the problems of power and the power of forgiveness and love.

Vilified by some and venerated by others as the FBI informant largely responsible for the imprisonment of two youths following the 2008 Republican National Convention, Darby was once a charismatic activist mythologized by the American Left for his daredevil aid work in New Orleans’ Ninth Ward in the aftermath of Hurricane Katrina. Informant meticulously constructs a portrait of his life—before and after the death threats—through intimate interviews with Darby and tense reenactments starring the man himself.
