Awakening in a hospital with complete amnesia following a devastating house fire, middle-aged Maeve finds herself at the mercy of her mercenary biological son. Rather than caring for his recovering mother, Ricky attempts to sell her into a sham marriage with an abusive creditor to settle gambling debts. Overhearing the despicable transaction, Maeve flees the clinic and enters an immediate municipal registry marriage with Hank, an older man she meets in the park.
Believing Hank is merely an impoverished retired laborer, Maeve moves into his modest cottage and lovingly cares for his household. In reality, Hank is an untouchable industrial billionaire whose five ultra-wealthy sons disguise themselves as broke blue-collar workers to test her sincerity. Charmed by Maeve's genuine warmth and resilience against Ricky's harassment, the hidden tycoon and his powerful sons mobilize their immense resources to shield her from harm.
