Officer Sarah Chen pulls over Robert “Ghost” McAllister for a broken taillight. When she approaches he sees familiar features and thinks of the daughter his ex took thirty-one years earlier. He remembers the lullabies, the birthmark, the photo he carried everywhere.
During the stop she says, “License and registration,” then later, “Mr. McAllister, I’m placing you under arrest for suspected DUI.” He’s cuffed; the breathalyzer reads 0.00.
At the station she finds a worn photo of a two-year-old—Sarah. She says, “I was adopted when I was three.” He says, “Thirty-one years, two months, and sixteen days.” They begin to compare memories and details.
DNA confirms the truth. A hard, awkward reunion follows: anger, explanations, forgiveness. She learns her adoptive parents lied to protect her; he never stopped searching.
They rebuild a relationship. She tells groups, “I arrested my father,” and calls it the “Best mistake I ever made.” They start rides together and a program pairing cops and bikers to help missing children.
