False Witness is the British title of the American thriller Zigzag, which in turn was partially inspired by the 1950 film D.O.A. George Kennedy plays an insurance investigator who learns that he is dying from a brain tumor. Hoping to provide for his family, Kennedy confesses to a murder he didn't commit, thereby collecting the reward money. During his murder trial, Kennedy collapses and is rushed to the hospital. Subjected to laser surgery, he emerges from the hospital completely cured--and now he must unravel the airtight case he's contrived against himself in court.
