Nora Whitmore had an enviable life, but was murdered by her husband Caleb during their wedding anniversary trip. At eight months pregnant, she fell into the Black Ridge Canyon and struggled to survive amidst numerous crises such as floods, abandoned hydroelectric power plants, and pursuers. She gradually discovered that behind this accident was a huge conspiracy planned by her husband and former friend Vivian, and the real target was not only her life, but also the family shares she inherited.
With the help of forest ranger Eli, Nora transformed from a fugitive to a counterattacker. She collects evidence to uncover the truth behind Caleb's fabricated accident and struggle for family control, and uses the distrust between enemies to launch a counterattack. When everyone thought she was dead, Nora returned with the truth, ready to take back everything that belonged to her and make those who betrayed her pay the price.
