The series showcases what happened in 1993 in Waco, Texas when cult leader David Koresh faced off against the federal government in a siege of 51 days. In the first episode, gunfire erupts when federal agents arrive at the Branch Davidian compound with a search warrant. Hostage negotiators later attempt to get the children out of the compound.
David Koresh was a member and later a leader of the Branch Davidians, a religious sect and offshoot of the Davidian Seventh-day Adventists, a movement based at the Mount Carmel Center outside Waco, Texas. His apocalyptic Biblical teachings attracted various followers. He became subject to allegations about polygamy and child sexual abuse by former Branch Davidian associates, although investigation by authorities found no conclusive evidence. Further allegations related to the Branch Davidians' stockpiling of weapons led the FBI to launch a raid on the group's Mount Carmel compound in February 1993.
