S1·E1 Episode 1

Artemis, a 30-year-old taekwondo champion, is forced to work at a gym after suffering an injury. There, she meets Tania, the wife of Russian tycoon Ivan, who asks her to privately train her husband's son, Dimitris. Although Artemis agrees at first, she soon realizes that Tania’s true intention wasn’t training—but caregiving, as Dimitris is on the autism spectrum. Encouraged by her best friend, Sissy, Artemis begins looking after Dimitris and gradually grows emotionally attached to him. But everything changes one night, when two hooded men break into the mansion to kidnap Dimitris.
