Though Damon once hid his five‑year secret love for her, genuine romance blooms between them amid mob power struggles. Obsessed and consumed by jealousy, Brad abandons Sienna and desperately tries to win Chloe back. After Sienna’s vicious schemes backfire and destroy herself, Brad loses everything and breaks down mentally.
