George Tiller was murdered in 2009, because he was a doctor in the United States who performed late-term abortions.
Following his assassination, there are now only four remaining doctors in the country who openly perform abortions on pregnant women during their final trimester. This small group of doctors have become the new number-one targets of the pro-life movement, yet continue to risk their lives every day to do work that many believe is murder, but which they believe is profoundly important for their patients' lives.
'After Tiller' follows them in their work, challenges them on their ethical decision-making, and explores the hostility they face on a day-to-day basis.
'After Tiller' is in selected cinemas across the UK from Friday 10 January. Watch the trailer below...
