After spending seven years in Oak Valley Rehabilitation Center battling severe PTSD, Mia is finally free—only to discover that her identical twin sister, Sophia, has been driven to the brink of death. Crushed by her husband's affair, years of emotional abuse, and a failed suicide attempt, Sophia has been committed to the very institution Mia just escaped.
Determined to uncover the truth, Mia secretly enters Sophia's mansion and witnesses the ultimate betrayal: Sophia's husband, Richard, openly romancing his mistress, Iris, while even Sophia's own son begs for the other woman to replace his mother.
Fueled by rage and armed with an identical face, Mia assumes Sophia's identity and infiltrates the household. As no one suspects the switch, she begins a carefully planned revenge, exposing every lie, punishing every betrayal, and making those who destroyed her sister pay for their cruelty.
