"It is hard to tell anybody – even the meanest person – that it is time to go.” – Reverend Carroll J. Pickett in At the Death House Door.

Pastor Carroll Pickett took his ministry to a Texas prison in 1982, in a state that vamped up its death penalty duties during that time period. During Pickett's remarkable career journey, he presided over 95 executions, including the world’s firs More..t lethal injection. After each execution, Pickett recorded an audiotape account of his trip to the death chamber.

The film also focuses on the story of Carlos De Luna, a convict Pickett counseled and whose execution troubled Pickett more than any other. He firmly believed De Luna was innocent, and the film tracks the investigative efforts of a team of Chicago Tribune reporters who have turned up evidence that strongly suggests he was.
