INCENDIARY: The Willingham Case tells the haunting story of Cameron Todd Willingham, a man executed for setting the fire to his house that killed his three daughters in 1991. It also documents the controversial Texas Forensic Science Commission, where Willingham's name has become an inflammatory theme. A key struggle between science and folklore is prevalent in this film that combines the mystique of scientific investigation, political drama and potential murder.

Through interviews with fire experts, legal experts and court footage, the directors explore the possibility that the science behind Willingham's conviction was shoddy and unreliable, yet ultimately led to a man's death. The directors contend the fire investigators on Willingham's case considered their profession to be more of an art than a science, and based their conclusions on what current fire experts call folklore. Whether Willingham was guilty or innocent wasn't the point of the documentary, the filmmakers said, but rather it was to present the different sides of the case and allow the audience to indulge in the mystery.

"I do have a serious problem with the manner in which he was convicted," Bailey said. "But we were more interested in the mystery this case created and the real facts. What we do know is what we tried to put on film."
