Seething and turbulent forces in American society led two men to their violent and tragic collision in Memphis, Tennessee, on April 4, 1968. Roads to Memphis from WGBH’s American Experience tells the fatefully entwined stories of assassin James Earl Ray and his target, Dr. Martin Luther King Jr. Based on the book by Hampton Sides, the program relies on eyewitness testimony from King's inner circle and the officials involved in Ray's capture and prosecution following an intense two-month international manhunt.

Watch it tonight at 9pm on WGBH 2.
