Climber Ava celebrates her seventh wedding anniversary with heir Ethan, only to discover she was divorced five years prior, and Ethan's current wife is none other than Serena, the very woman responsible for her fatal fall. Heartbroken, Ava hires a hacker to erase her identity, determined to return to the International Climbing Masters as "Aquila." During preparations, she witnesses Ethan and Serena's betrayals, is drugged, framed, and even whipped by Ethan in a boathouse, ultimately forced to jump into the sea. After being rescued, with the help of her childhood friend Sebastian and his sister Celia, Ava uncovers the truth, restores her reputation, and wins the International Climbing Masters finals. Meanwhile, overwhelmed by remorse and the truth, Ethan fulfills his vow that "those who betray love will be executed," taking his own life. Ava eventually reunites with Sebastian, who has always silently protected her, and begins a new life together.
