A video showing nail bites shows a 12-year-old boy clinging desperately to the tree branch after he and his 13-year-old friend were caught in strong currents while visiting a stream in Indianapolis after school on Monday .
The two children were saved by heroic firefighters after they were spotted fighting for two other people, who called 911.
In the images of the rescue, the first responders are curled up around the 12-year-old boy, while shuffling out of the water against the current in a group.
To get there, IFD said they needed to navigate through a wooded area and drop a four-foot drop on a sand bank downstream of the child.
A 12-year-old boy was seen clinging desperately to a tree in a fast-moving stream in Indianapolis when his friend, aged 13, was stuck in another part of the river, nearby.
The firefighters were called to the scene and were able to get the two boys safely back to the coast. The rescue process was more difficult for the youngest of the boys, as it was in a more secluded part of the stream
From there, firefighters threw a rope bag upstream to hold on. They dragged him towards them, put him in a life jacket and took him back to the wooded area.
The young man was treated by emergency medical technicians and taken to the hospital.
For its 13-year-old counterpart, things were a bit simpler.
Because it was immediately visible to firefighters, and was able to hold on to a rope, the older child was easy to extract from Fall Creek.
"It is not clear how long the boys were in the water, however, they said it was sometime after school," said a statement from the Indianapolis Fire Department.
"When asked if the children had previously played in the water in that area, they both said no and had only ridden their bicycles in the area today."
Firefighters say the rain has increased water levels and strengthened the flow, and advises people to stay out of the rivers until water levels drop and the current stabilizes.

Both boys were taken to the hospital and it is understood that they are doing well
