Caleb, a wealthy businessman, is shocked when he encounters Michelle, a new janitor at his office who bears a striking resemblance to his late mother, believed to have died 28 years ago. Intrigued by the resemblance and a peculiar scar on her arm, Caleb asks Michelle to take a DNA test. The results reveal the impossible: Michelle is his biological mother.

Confused and betrayed, Caleb seeks answers from his father, William, who had always claimed Caleb’s mother died in a car accident. Caleb and Michelle hatch a plan to confront William without revealing the truth immediately. Michelle visits William under the guise of a saleswoman. William is startled by her resemblance to his late wife and even more so when she intuitively locates the hidden light switch in his kitchen, something only someone familiar with the house would know.

Later that night, Caleb follows his father as he sneaks into Michelle’s home with sinister intentions. William, believing he’s silencing a ghost from his past, is caught in the act of stabbing a decoy figure in Michelle’s bed. The police arrest William on the spot.

In the interrogation room, the truth unravels. William confesses that Caleb’s mother didn’t die in an accident but was instead left for dead after suffering amnesia. Caleb realizes his father had been hiding a dark secret, but now, mother and son are finally reunited.
