On the evening of Father's Day, 2005, separated husband Robert Farquharson was driving his three young sons back to their mom's house when the car veered off the road and plunged into a dam.

The court case that followed became a national obsession--a macabre parade of witnesses, family members, and the defendant himself, each forced to relive the unthinkable for an audience of millions.
