Suleiman al-Yusuf is a father of seven.
He lives outside Damascus and works odd jobs.
Twelve years ago, his son Shadi went missing, and he's been looking for him ever since.
Our colleague Ben Solomon talked to Suleiman last December.
What were your first impressions of him?
So when we first met him, he was just very kind, very gentle, and really just soft-spoken.
It was clear that he didn't come from a lot of money,
that he was a working-class guy, and that he just didn't know really where to turn.
He didn't know how to approach this search, but he was going to do whatever he could.
Suleiman showed Ben the only clue that he had that his son was alive, a video.
The video shows men being released from prison after the fall of Syria's dictator.
There, in the crowd, Suleiman pointed to one man, who he said is his son.
He said, when I saw the video, I knew.
I said, that's Shadi.
He also said, if you put him among a million people, I could still pick him out.
And when he showed us the video, I mean, it was shocking.
Ben makes documentaries for The Wall Street Journal and decided to follow Suleiman's journey.
It was like, oh, this is, I mean,
I immediately thought, wow, this is going to end with a happy ending.
Like, he's going to find his son.
