100 Proof is a 1997 independently produced American thriller film written and directed by Jeremy Horton.[a] Shot on location in Kentucky, it is based on the true story of a killing spree that took place in Lexington in 1986. Two women, LaFonda Fay Foster and Tina Hickey Powell, murdered five people in the real-life incident. The film's supporting cast includes Jim Varney, who portrays the drunk, violent, incestuous father of one of the two women at the center of the story. Varney's role is radically different from the humorous Ernest P. Worrell character for which he was best known.
