During the call, the female caller tells the operator, "There is a car accident ... one vehicle ... it's upside down." She continues, "My husband and three other guys just pulled the boy out."

One of the men was Dempsey -- who helped pull the 17-year-old out of the wreckage and even called the kid's mother to tell her he was okay.

The boy was airlifted to a nearby hospital. He suffered a concussion and a "stretched" optic nerve -- but he's expected to make a full recovery.

Dempsey later stopped by the hospital to make sure the kid was okay. McDreamy, indeed. - more on this story
