While Mary is away on a business trip in Los Angeles, her husband Michael indulges in an affair with Lucy, a hotel maid. What he doesn’t realize is that Lucy has a hidden motive—revenge. Years earlier, Lucy’s sister Samantha had worked as a maid for Mary and Michael. A misunderstanding led Mary to believe Samantha was having an affair with Michael. Instead of clearing Samantha’s name, Michael falsely accused her to protect his actual affair. Samantha was fired, fell into poverty,

lost her unborn child, and eventually took her own life. Lucy only learned the truth after receiving her sister’s final letter—and swore to get justice. Now, Lucy plays along with Michael’s advances, waiting for the perfect moment to ruin him. When Mary unexpectedly returns to the hotel, Michael scrambles to hide Lucy, barely managing to deceive his wife. But Mary remains suspicious and corners Lucy later, pressing her with questions and even demanding to see hotel security footage. Lucy,thinking fast, manipulates the footage to throw Mary off the scent. Meanwhile, Michael is being blackmailed and is secretly siphoning thousands from Mary’s bank account. The blackmailer threatens to expose his affair—what Michael doesn’t realize is that Lucy is the one behind the calls. Eventually, Michael thinks he’s in the clear. With Mary gone again, he returns to the room, only to be confronted by two Lucys—one at the door, and one inside. Mary, disguised in a maid’s uniform,

exposes everything. Michael pleads, but it’s too late. As he begs for forgiveness, Lucy delivers the final blow—revealing she is Samantha’s sister. Her plan has worked. Michael is ruined, and Mary is finally aware of her husband’s betrayal and her own past mistake. Lucy walks away, not seeking sympathy or pity. She donates the blackmailed money to a charity for orphaned children and whispers into the wind, “I got your revenge, Sammy.”
