Dwayne "The Rock" Johnson and Zac Efron have been filming the "Baywatch" at Memorial University Medical Center in Savannah and The Rock took a break to visit some patients. One in particular brought a mom to tears.

After surprising young patients in the pediatric ward, The Rock decided to "call an audible," as he put it, and added one more stop on the tour. Read his inspiring message below:

"While I was visiting the Pediatric Specialty Ward surprising the kids, I got word from my team that there was a mom who was pleading with our production staff, that I go upstairs to her son's room to give him a much needed big surprise. Since he's older he's in the main hospital and not in pediatric care.

We were shooting 'Baywatch'  scenes outside of the hospital, but instead of heading back to shoot I called the audible, put production on hold and went upstairs to see this young man.

I walked in and his smile lit up the room! And I mean lit that room up!;) We talked for a while about his family, his school and how hard he's working to eventually graduate AND we talked about how COOL all his scars are from his multiple surgeries - from his head to his chest - those scars are badges of honor and the reminder of how beyond tough this kid is.

Right before I left his mom looked at him and said, 'Christopher I can't give you anything, but I'm so happy I could give you this today...' and she started to breakdown, which was captured in this pic.

Made me think to give so much credit to these parents who would do anything to take their kid's pain away and ANYTHING to bring a smile to their faces. As a papa bear I understand.

Glad this mom brought a smile to Christopher's face."
