It started with a husband's obsession with the divorce movie "War of the Roses" and then escalated to 12 hours, of terror as he held his soon-to-be ex-wife hostage in their very own home. This divorce Armageddon played out in real time to negotiators and reporters and was all caught on audio tapes, offering sensational insight into the mind of a man out of control and a woman fighting for her life. ABC News Anchor Robin Roberts reports a harrowing story with chilling details about an epic divorce, kidnapping, miraculous escape and shocking testimony that left a courtroom speechless. The report, with exclusive interviews and audio tape, airs on "20/20" on FRIDAY, JANUARY 27 (10:00-11:00 p.m., ET) on the ABC Television Network.

When divorced mother of two Nancy Tyler met successful TV producer Richard Shenkman, she thought she had finally found the man of her dreams. Shenkman married Tyler, adopted her two children, and together they built a comfortable life in an upscale Connecticut community. But several years into the marriage, Shenkman's controlling and abusive behavior proved to be too much for Tyler. She thought divorcing him would end her shattered dream, but the nightmare was only just beginning. Refusing to accept the divorce, Shenkman went on a violent rampage, stalking Tyler, even burning their beach house to the ground before kidnapping her at gun point and holding her hostage in the home they once shared. Will Nancy Tyler ever truly be free?
