“At the Death House Door” (9 p.m., IFC): The Rev. Carroll Pickett left the pulpit in

“At the Death House Door” (9 p.m., IFC): The Rev. Carroll Pickett left the pulpit in Huntsville, Texas, to become chaplain of the town’s Walls prison. But shortly after he began work at the infamous facility, Texas resumed executions. Pickett was named “death house chaplain,” with his duties described by the warden as winning the trust of the condemned prisoners in those last few hours, so “they won’t try to fight at midnight.” From 1982 to 1995, Pickett ministered to 95 doomed inmates, including Ignacio Cuevas, the lone surviving inmate from the 1974 prison siege that claimed the lives of two of Pickett’s own church parishioners. The documentary “At the Death House Door” profiles Pickett and the burdens of this job, including his shifting position on capital punishment. A story of doubts that torment a man of faith, this film is by Steve James and Peter Gilbert, who also made the much-acclaimed “Hoop Dreams.”
