Jeremy Davies stars as convicted killer Charles Manson in this new television movie based on the true story of the August 1969 Tate/LaBianca murders, as chronicled in the bestselling book Helter Skelter by Vincent Bugliosi. Almost 35 years ago Manson's followers, at his instruction, brutally massacred seven people over two consecutive nights in Los Angeles and scrawled bloody messages on the walls of the crime scenes. The first night, director Roman Polanski's wife, eight-month-pregnant actress Sharon Tate, was murdered along with coffee heiress Abigail Folger, Jay Sebring, Voytek Frykowski and Steven Parent. The second night, supermarket chain president Leno LaBianca and his wife, Rosemary, were found stabbed to death in their home.
