Prepare to watch a hero do his thing.

This is incredible footage of a fireman in Buenos Aires, Argentina saving a baby from an apartment building that caught fire. You can see the man on the outside of the balcony taking the youngster from someone inside and then cradling the child in his arms as he gingerly begins his descent down to safety.

It's unclear how the blaze started, but reports suggest it was ignited at a nearby warehouse.

It's also unclear if the adult who handed off the baby fled to safety.

What is clear? This firefighter acted fearlessly to save someone.
