Not everyone grows up knowing who his father is, and people who don't know their biological fathers when they're children often search for that person as they get older. "Finding My Father" helps people in that situation locate the men they are looking for. With social media, private investigators and distant relatives at their disposal, the subjects attempt to piece together details about their fathers' lives that they hope can lead them to the men's current whereabouts. During the investigations, surprising information is sometimes uncovered, such as one person finding out that he has lived an hour away from his dad for his entire life without knowing it. For most of these people, finding their fathers will be like finding a piece of themselves.
