Isolde, devastated by her daughter Effie's death and husband Grayson's affair with Belle, commits suicide and is reborn a year before the tragedy. Empowered, she confronts Grayson, exposes his infidelity, and leaves him, taking Effie. Reclaiming her past as a brilliant aerospace engineer, "Valkyrie," Isolde secures a job with Arland Roth and begins dismantling Grayson's life. She exposes Belle's incompetence and Grayson's neglect, especially when Effie falls critically ill and Grayson ignores her. Discovering Effie's hidden genius, Isolde enters the International Space Settlement Design Competition (ISSDC) to publicly challenge SkyLine, using her superior skills to expose their stolen designs and shoddy work. Simultaneously, she works to save her mother's failing company, vowing to make Grayson and Belle pay and build a secure future for Effie.
