Exploring what could've happened to the boys, the episode looks at the case of Carlina White, who was taken from Harlem Hospital when she was only 19 days old. A woman dressed as a nurse had smuggled Carlina out when her parents brought her in for a fever. Over two decades later, Carlina went by the name Nejdra "Netty" Nance. While applying for insurance, she discovered that her birth certificate had been forged. Browsing archives from the National Centre for Missing and Exploited Children, Netty noticed that Carlina's baby picture looked like her own child. After a DNA test, she discovered that she was Carlina. Ann Pettway, the woman who raised her, had abducted Carlina after suffering a series of pregnancy losses.
