Victor, patriarch of the Sterling family, welcomed his supposed long-lost son Ryan three years ago, unaware Ryan was an orphan impostor. The real heir Lucas was betrayed by his girlfriend Vivian, trafficked to Blackstone Mine as forced labor. Ryan forged a matching sun birthmark to get close to Victor, scheming to embezzle the family wealth. Victor chanced upon the abused Lucas with the same birthmark, ran a covert DNA test and confirmed his bloodline. Forewarned of the murder plot, Victor staged a mine raid and saved the injured Lucas. Reunited, Lucas told the story of the cruel frame-up. Victor worked with police to bust the mine operation, determined to hunt down the hidden mastermind.
