Story of a refugee boy/girl 
Witnessing their mother being shot in front of them and her words to them, words of reality and inspiration
Then the rest of the song is the child's call for someone, no matter who to help them, to take them out of this situation, the devastation, the trauma
He's saying that he's in a completely hopeless state and needs someone to reach in and pull him out, because he can't do it himself. It's a call to us who can, to stand up for these people.
The last phrase is an inspiring phrase coming from the Mother which is propelling him to live.

Here the lyrics:

Stand by me

Hold your breath, close your eyes
I'm going under, one last time
Hold your breath, close your eyes
I'm going under, I'm gonna die.

Pre-Chorus:
Stand by me, stand by me
Won't you stand by me, stand up for me
Will Someone stand by me, stand by me
Stand by me, stand up for me

Chorus:
There's nowhere to run, 
there's nowhere to hide
Will someone draw near, from the other side

Pre-Chorus:
Stand by me, stand by me
Won't you stand by me, stand up for me
Will Someone stand by me, stand by me
Stand by me, stand up for me

Outro:
Hold your breath, close your eyes
Going under, but you're gonna fly
