On her wedding anniversary, Yeo-wool survives a horrific accident. A year later, she and her son I-chan transfer to HSC International School for a fresh start. But her hidden past soon spreads among the mothers.

After I-chan's accident, Yeo-wool and I-chan are shunned. Only Na-yoon reaches out. Then Yeo-wool receives white roses and mysterious texts sent to her late husband's old phone, hinting that his death may not have been an accident.

A mysterious young man keeps crossing paths with Yeo-wool. Determined to uncover the truth, she hires an investigator. The CCTV footage reveals a parent chasing I-chan.

While Jae-in discovers I-chan's father's belongings in his bag, Na-yoon approaches Yeo-wool with a chilling expression. Meanwhile, Ji-seon schemes to drive Yeo-wool out, as a warning echoes: "In a strange place, beware those closest to you."
