Terror from Within: Jason Van Vleet's documentary explores how a plan to overthrow the government conceived in 1983 by home-grown extremists lead to the tragic 1995 bombing of the Alfred P. Murrah Building in Oklahoma City. Van Vleet's film includes interviews with officials who investigated the terrorist attack and a taped confession by one of the perpetrators of the bombing, and looks at domestic terror groups that are still operative years after the attack.
