When a beautiful woman named Rebecca Zahau is found hanging naked from a balcony of one of the most expensive mansions in Coronado, California, bound and gagged, authorities are quick to rule her death a suicide. As new, troubling facts emerge about the case, suspicion begins to fall on her brother-in-law, who cut her down and tried to save her as he talked to 911. Nothing is as it seems as airtight alibis slowly unravel, and even the intricate clove-hitch knots she supposedly tied around her wrists are removed from cardboard tubes and presented to a spellbound jury.
