Help with sub-folder rule [driving me bonkers :)]

I've been trying every combination possible for the last few days and can't for the life of me figure this out :/ Help?
Please? 
Structure:
/Photo/Vacation/1.mp4
/Photo = parent/root folder
Once the Vacation folder with the mp4 gets dropped in there. How do I make it so Hazel searches for all files named "1.mp4" that's 1 sub-folder depth away or greater (in the Vacation folder in this case... basically, I want a rule that will look into each folder that gets dropped into the Photo parent folder), and then move it to the trash?
I've tried everything in viewtopic.php?f=4&t=470 ... any every combination as possible that I can think of, but there's always a gotcha.
